Learn Retail Arbitrage, Online Arbitrage and Amazon to Amazon from two brothers who actually do this — built exclusively for the UK marketplace.
Fulfilment by Amazon (FBA) lets you sell products on Amazon while they handle storage, packing, shipping, customer service and returns — so you can focus on sourcing and growing.
Find profitable products from UK retail stores, online retailers, or Amazon itself at prices below what they sell for on Amazon.
Label your products and send them to Amazon's UK fulfilment centres. They store your inventory in their warehouses until it sells.
When a customer orders your product, Amazon picks, packs and ships it — often with Prime next-day delivery. They handle all customer service too.
Amazon deposits your sales revenue into your bank account every 14 days, minus their fees. You keep the profit and reinvest to grow.
Amazon UK continues to expand year after year. UK third-party sellers are seeing consistent revenue growth — and the FBA model is at the centre of it.
Amazon FBA removes the hardest parts of running an e-commerce business — logistics, customer service, and delivery — so you can focus on finding profitable products.
Start with as little as £200–£500 in sourcing capital. No need for a warehouse, staff, or website. Amazon provides the platform and the customers.
Source products around your schedule. Many UK sellers run Amazon FBA alongside a full-time job, scaling up when they are ready to go full-time.
Go from a few hundred pounds a month to a full-time income. UK sellers using RA, OA and A2A regularly scale to £5,000–£10,000+ monthly revenue.
No packing orders at your kitchen table. Amazon stores, picks, packs and ships every order. They also handle returns and customer service queries.
FBA products automatically qualify for Amazon Prime. That means next-day delivery, higher search rankings, and significantly more sales.
Amazon UK revenue continues to grow year on year. More customers are shopping online than ever — and third-party sellers are capturing a bigger share.
This is what a typical UK FBA seller's revenue journey looks like — starting small, learning the fundamentals, and scaling up over the first 12 months.
FBA Mastery covers every major arbitrage model used by profitable UK sellers — you choose the one that fits your budget and lifestyle.

Callum leads the Retail Arbitrage and operations modules in FBA Mastery. He started selling on Amazon UK with a small amount of startup capital, spending weekends scanning stores before building the systems that allowed him to scale.
His focus inside Gerrard FBA Academy is on the practical, unglamorous side of Amazon FBA — the prep, the shipping, the account health, the cash flow. The stuff that actually determines whether your business survives or struggles.
Ayron specialises in Online Arbitrage and Amazon to Amazon — the more scalable, technology-driven side of the business. He built his sourcing systems around tools like Tactical Arbitrage and Keepa, and now generates consistent deal flow with minimal manual work.
Inside Gerrard FBA Academy, Ayron teaches the OA and A2A modules with the same systems he uses in his own business — nothing theoretical, everything tested in the UK market.
No other UK Amazon FBA course is built around two siblings with different specialisms. You get real variety — two styles, two areas of expertise, two honest perspectives on what works and what doesn't in the UK marketplace.

Retail Arbitrage — walking into a physical shop, scanning products, and reselling them on Amazon for a profit — remains one of the most accessible ways to start selling on Amazon FBA in the UK. But not all shops are created equal. Some consistently deliver clearance opportunities, while others are a waste of petrol.
After years of sourcing across the UK, here are the ten stores we keep going back to — and what makes each one worth your time.
B&M is the undisputed king of UK Retail Arbitrage. Their stock rotates quickly, clearance is frequent, and many products are exclusive to the store — meaning less competition on Amazon. Focus on the end-of-aisle displays and the clearance section at the back. Homeware, toys, and health and beauty are the strongest categories.
Similar to B&M but with a slightly different product mix. Home Bargains runs its own clearance cycles and often stocks branded items at prices well below RRP. The health and beauty aisle is particularly strong — look for branded shampoos, skincare, and supplements that sell well on Amazon UK.
Tesco Extra stores have the biggest clearance sections, typically marked with yellow and orange reduced stickers. The key is timing — visit after seasonal transitions (January, post-Easter, September) when Tesco slashes prices on seasonal stock. Electronics, toys, and branded groceries tend to yield the best margins.
Smyths runs aggressive clearance, especially after Christmas and through the summer. Their advantage is that many toy lines are exclusive to the UK or to Smyths specifically, which limits the number of Amazon sellers competing on the same listing. Always check the back wall and end-of-aisle clearance bays.
The Range is underrated for RA sourcing. They stock a wide mix of home, garden, crafts, and seasonal items — many of which are hard to find online. Look for branded products mixed in with their own-label items. Craft supplies and garden tools are particularly strong categories during spring and summer.
Argos clearance is hit-or-miss, but when it hits, the margins are excellent. Check the Argos website before visiting to see what is on clearance in your local store. Electronics, small kitchen appliances, and branded toys are the best categories. Some sellers use the Argos click-and-collect system to reserve clearance items online before picking them up.
Boots is a goldmine for health, beauty, and personal care products. Their Star Offers and 3-for-2 promotions often create margins that work well on Amazon. Premium skincare, branded supplements, and fragrance gift sets (especially around Christmas) are consistently profitable. Check the back of the store for reduced-to-clear items.
Now operating under new ownership, Wilko stores continue to stock affordable homeware, cleaning supplies, and garden products. Their branded items often appear at lower prices than other retailers, making them viable for FBA arbitrage. Focus on seasonal items and cleaning products from known brands.
Sainsbury's larger stores have general merchandise sections — clothing, homewares, toys — that go through regular clearance cycles. The Tu clothing brand is Amazon-restricted, but other general merchandise like kitchen gadgets, toys, and stationery can yield solid returns. Check after seasonal changeovers for the deepest discounts.
TK Maxx requires more experience to source effectively because their stock is unpredictable. However, that unpredictability is also the advantage — you can find branded products at deep discounts that few other sellers will have spotted. Fragrance, premium kitchen brands, and branded fitness accessories are the strongest categories.
Pro tip: The best day to visit most UK retail stores for clearance is Tuesday or Wednesday — that is when many chains process their markdowns from the weekend. Avoid Saturday afternoons when the good stuff has already been picked over.
Retail Arbitrage is not dead — but it has become more competitive. The sellers who succeed are the ones who build efficient sourcing routes, know their stores inside out, and understand which categories to focus on in each location. Scanning everything is slow. Scanning strategically is profitable.
If you are just getting started, pick two or three stores from this list and learn them properly before trying to cover all ten. Depth beats breadth when you are building your sourcing instincts.
FBA Mastery Module 6 covers Retail Arbitrage in detail — including live in-store sourcing walkthroughs and a complete UK seasonal sourcing calendar.
See the Full Course →If you are selling on Amazon FBA, Keepa is arguably the single most important tool in your stack. It tracks the complete history of every product on Amazon — price changes, sales rank movement, Buy Box ownership, and more. But most new sellers look at a Keepa chart and have no idea what they are actually seeing.
This guide breaks down every element of a Keepa chart so you can make confident buying decisions.
Keepa is a browser extension and website that tracks Amazon product data over time. While Amazon only shows you the current price and sales rank, Keepa shows you the full history — weeks, months, or even years of data. This is critical because a product that looks profitable today might have been at that price for one day out of the last six months.
The main Keepa graph shows price over time. There are several coloured lines, each representing a different seller type:
What you want to see depends on your strategy. For most FBA arbitrage sellers, the key question is: when the orange line disappears (Amazon drops off the listing), does the blue line stay high enough for your margin to work?
The green line on a Keepa chart shows the product's Best Sellers Rank (BSR) over time. This is the most important indicator of how fast a product sells. The key principles are:
Rule of thumb: In most UK categories, a BSR under 100,000 means the product is selling regularly. Under 30,000 means it is selling well. Under 5,000 means it is selling fast. But these thresholds vary significantly by category — Keepa makes it easy to see the actual velocity.
Keepa tracks who holds the Buy Box over time. This is shown in the "Buy Box" tab and tells you whether Amazon dominates the Buy Box, whether it rotates between sellers, or whether there is an opportunity for a new seller to win it.
If Amazon holds the Buy Box 95% of the time, you are unlikely to get many sales as a third-party seller — even if your price is competitive. If the Buy Box rotates among several FBA sellers, that is a much better opportunity.
The number of sellers on a listing directly affects your share of the Buy Box and your ability to sell at a profitable price. Keepa shows you how the seller count has changed over time. A listing that had 3 sellers last month and now has 15 is a red flag — too many sellers have spotted the same opportunity, and the price is likely about to drop.
Before you buy any product for FBA, run through this Keepa checklist:
Make sure your Keepa account is set to the Amazon.co.uk marketplace. The default is often Amazon.com, which will show you completely irrelevant data. You can change this in the Keepa extension settings or on the website. Also enable the browser extension overlay so you see Keepa data directly on every Amazon product page without having to navigate away.
FBA Mastery Module 5 covers Product Research Fundamentals — including a full Keepa masterclass, Seller Amp setup, and how to set margin targets for UK arbitrage.
See the Full Course →One of the first questions every new UK Amazon FBA seller asks is: should I register as a sole trader or set up a limited company? The answer is not as straightforward as most course creators make it sound, and getting it wrong can cost you money or create unnecessary admin.
Here is the honest answer, based on where most UK sellers actually are when they start.
| Sole Trader | Ltd Company | |
|---|---|---|
| Setup cost | Free | £12–£50 |
| Setup time | Same day | 24–48 hours |
| Annual accounts | Self-Assessment | Company Tax Return + Confirmation Statement |
| Personal liability | Unlimited | Limited to company assets |
| Tax efficiency | Lower at low profit | Better above ~£30–40k profit |
| VAT threshold | £90,000 | £90,000 |
| Perceived credibility | Lower | Higher |
For most new Amazon FBA sellers, starting as a sole trader is the right call. Here is why:
The downside is that you are personally liable for all business debts. In practice, for most FBA sellers buying retail stock, this risk is low — but it is worth understanding.
There are three main triggers for switching to a limited company:
At this level, the tax advantage of a limited company starts to kick in. Corporation Tax (currently 25% for profits over £50,000, or 19% for small profits) combined with taking a small salary and the rest as dividends is usually more tax-efficient than paying income tax and National Insurance as a sole trader.
If you are scaling up and carrying significant stock, a limited company ring-fences your personal assets. If something goes wrong — a supplier dispute, a customer claim, an unexpected Amazon clawback — your personal savings and home are protected.
Banks and lenders prefer limited companies. If you need a business credit card, a loan, or an overdraft to fund stock purchases, an Ltd company with proper accounts gives you more options. Some Amazon lending programs also favour limited companies.
Important: Switching from sole trader to Ltd is straightforward but involves some admin — new Amazon Seller Central account or ownership transfer, new bank account, notifying HMRC. Plan the transition rather than doing it mid-season.
This applies to both sole traders and limited companies. You must register for VAT when your taxable turnover exceeds £90,000 in any 12-month rolling period. Note that this is turnover (total sales), not profit. Many FBA sellers hit this threshold faster than they expect because Amazon gross sales include the selling price plus any shipping charges.
Once VAT-registered, you charge 20% VAT on your sales but can reclaim VAT on your purchases. For many FBA sellers buying from VAT-registered retailers, the net impact is manageable — but it does add complexity to your bookkeeping.
Start as a sole trader. Focus your energy on learning how to source, list, and sell rather than on company formation and accounting structures. When your monthly profit consistently exceeds £2,500–£3,000, speak to an accountant who understands e-commerce and Amazon FBA — they will advise you on the exact right time to switch based on your specific numbers.
Do not let business structure become a reason to delay starting. You can always switch later, and the cost of waiting is almost always higher than the cost of starting as a sole trader.
FBA Mastery Module 2 walks you through setting up your UK business — sole trader vs Ltd, HMRC registration, VAT, bookkeeping, and bank accounts.
See the Full Course →Amazon to Amazon — or A2A — is one of the most misunderstood sourcing models in the UK FBA community. Some sellers swear by it, others dismiss it entirely. The truth is somewhere in between, and whether it works for you depends on how you approach it.
A2A means buying products from Amazon itself — at a reduced price — and then reselling them back on Amazon at the regular price. It sounds counterintuitive, but Amazon frequently sells products below their typical market value through several channels:
The basic workflow is:
Key insight: A2A works because Amazon's pricing is not static. The price you buy at during a Lightning Deal or from the Warehouse may be significantly lower than the price the same product sells for the following week. You are buying the timing gap, not a fundamentally different product.
A2A is heavily tool-dependent. Without the right software, you will miss the deals before they are gone. The two essential tools are:
Yes — but with important caveats:
A2A works best as a complement to RA or OA, not as a standalone model. The ideal scenario is that you are already sourcing through other methods and you add A2A as a low-effort way to pick up additional profitable stock — especially during deal events like Prime Day, Black Friday, and the January sales.
If you are a complete beginner, start with RA or OA first. Learn the fundamentals of product research, listing, and shipping. Then add A2A once you are comfortable with Keepa and understand how to read pricing data quickly.
FBA Mastery Module 8 covers Amazon to Amazon end-to-end — including Keepa alert setup, Warehouse Deal workflows, and how to avoid the common pitfalls.
See the Full Course →When you start selling on Amazon FBA, you will prep and ship everything yourself. Labels on the kitchen table, bubble wrap on the floor, trips to the Post Office or UPS drop-off point. It works — but it does not scale. At some point, the prep becomes the bottleneck, and that is when most sellers start thinking about a prep centre.
A prep centre is a warehouse that receives your stock, inspects it, labels it with FNSKU barcodes, poly-bags or bubble-wraps items as required by Amazon, and then ships it into Amazon FBA on your behalf. You never touch the stock.
For Online Arbitrage and A2A sellers, this is especially powerful — you can have orders delivered directly from retail websites to your prep centre, cutting out the middleman (your living room) entirely.
There is no magic number, but here are the signals that you are ready:
UK prep centre pricing typically breaks down as follows:
| Service | Typical Cost |
|---|---|
| Receiving and inspection | £0.20–£0.50 per unit |
| FNSKU labelling | £0.15–£0.30 per unit |
| Poly-bagging | £0.20–£0.40 per unit |
| Bubble-wrapping | £0.30–£0.60 per unit |
| Box and ship to Amazon | £0.30–£0.80 per unit |
| Storage (if needed) | £0.50–£1.50 per unit per week |
All-in, expect to pay between £0.80 and £2.00 per unit for standard prep. This needs to be factored into your profit calculations — but for most sellers doing volume, the time saved more than covers the cost.
Important: Always factor prep centre costs into your buying decisions before purchasing stock. A product that is profitable at self-prep margins may not work once you add £1.50 per unit in prep fees. Adjust your minimum margin thresholds accordingly.
Not all prep centres are equal. Here is what to evaluate:
Many successful UK sellers use a hybrid model — they self-prep RA stock that they physically pick up from stores, and send OA and A2A purchases directly to a prep centre. This gives you the cost savings of self-prep where it is easy, and the scalability of a prep centre where it matters most.
Start by self-prepping everything. Once you are consistently profitable and time-constrained, test a prep centre with a small batch. If the quality and turnaround meet your standards, gradually shift more volume across.
FBA Mastery Module 9 covers prepping and shipping to Amazon — FNSKU labels, Amazon's prep requirements, shipment plans, UK carriers, and a full UK prep centre directory.
See the Full Course →Cash flow is the number one reason profitable Amazon FBA businesses fail. Not lack of sales, not bad sourcing, not account suspensions — cash flow. Understanding the 14-day payout cycle and planning around it is one of the most important things you can do as a UK seller.
Amazon pays sellers every 14 days. That means from the moment a customer buys your product, it can take up to two weeks for that money to reach your bank account. In practice, the cycle often looks like this:
So your £500 investment might not fully return to your bank for nearly a month. Meanwhile, you have found more deals and want to buy more stock. This is the cash flow crunch — you are profitable on paper but broke in reality.
Most new sellers calculate profit but not cash flow. They see a product with a 30% ROI and think it is a great buy. And it is — if you can afford to wait for the money. But if buying that stock means you cannot buy the even better deal you find tomorrow, your growth stalls.
The golden rule: Never invest more than you can afford to have locked up for 30 days. If your total cash is £2,000, invest a maximum of £1,500 in stock and keep £500 as a buffer. As your payouts start flowing, you can reinvest and grow.
Use a tool like Sellerboard or a simple spreadsheet to track when money goes out and when it comes back. Know your payout dates and plan your buying around them. The day after a payout is when you should be buying stock — not the day before.
A business credit card with a 30–56 day payment cycle can bridge the gap between buying stock and receiving Amazon payouts. Buy stock on the credit card, sell it through FBA, and pay the credit card off with your Amazon payout before interest accrues. This effectively doubles your buying power without any interest cost — but only if you are disciplined about paying it off in full.
When cash is tight, prioritise products with a low BSR (high sales velocity). A product that sells in 3 days returns your cash faster than one that sits in Amazon's warehouse for 3 weeks. Speed of sale matters more than margin percentage when you are cash-constrained.
It is tempting to buy 50 units of a great deal. But if those 50 units take 8 weeks to sell, you have tied up capital that could have been used for 10 different products that each sell in 2 weeks. Spread your risk and your capital across multiple products rather than going deep on a few.
Once your Amazon account is established (usually after a few months of consistent selling), you may be eligible for more frequent payout options. Check your Seller Central payment settings — some sellers can access their funds more often than the standard 14-day cycle.
Think of cash flow as the heartbeat of your business. Profit is what makes the business worth running, but cash flow is what keeps it alive. A business with £5,000 profit on paper but £0 in the bank cannot buy stock, pay prep fees, or cover VAT — and it certainly cannot grow.
The most successful FBA sellers we know are not the ones with the best margins — they are the ones who manage their cash intelligently and reinvest at the right times.
FBA Mastery Module 12 covers managing finances and cash flow — Sellerboard setup, payout cycles, credit card strategies, and Amazon Lending.
