Selling on Amazon Review 2026 | Worth the Fees, or a Trap for Small Sellers?

Overall score: 7.4/10 Starting price: £0.75 per item or £25/month Free trial: No (Individual plan has no monthly fee) Best for: Sellers who want access to Amazon’s buyers and can protect their margins from the fees

No other channel puts your product in front of as many buyers as Amazon. That is the pull. The push-back you hear from sellers is just as consistent: fees stack up, competition is brutal, and Amazon makes the rules. Both things are true, and whether Amazon works for you comes down to numbers, not opinions. This review covers how selling on Amazon works in 2026, what the marketplace and FBA really cost, and which sellers come out ahead.

What Selling on Amazon Actually Is

Amazon Marketplace lets third-party businesses list products alongside Amazon’s own, and third parties now make up the majority of units sold on the site. You run your account through Seller Central, and you choose how orders get delivered. With FBM (Fulfilled by Merchant), you store and post orders yourself. With FBA (Fulfilment by Amazon), you send stock to Amazon’s warehouses, and Amazon picks, packs, delivers, handles returns, and gives your listings the Prime badge. Most established sellers use FBA for their main lines because Prime eligibility lifts conversion, and FBM for slow movers or oversized items where warehouse fees hurt.

Getting Started

You pick one of two plans. The Individual plan has no monthly fee and charges £0.75 per item sold, but it locks you out of advertising, bulk listing tools, and the Buy Box. The Professional plan costs £25 a month before VAT and removes those limits. The maths flips at about 34 sales a month, so most serious sellers go Professional early. Setup means registering with ID and bank details, then listing against existing product pages or creating new ones. Expect verification to take days, not minutes, and expect some categories to require approval before you can list at all. If you go the FBA route, you also prep and label stock to Amazon’s spec before shipping it in, and mistakes there get charged back to you.

Pricing: What You Actually Pay

Three costs matter. First, the referral fee on every sale, typically 8 to 15% of the price depending on category, with a £0.25 minimum. In practice many UK categories now come to about 15.3% once the digital services tax surcharge is folded in. Second, the plan fee. Third, FBA charges if you use it: fulfilment from roughly £2.19 per small item, plus monthly storage that jumps from about £0.75 to £2.40 per cubic foot between October and December. The 2026 fee round actually cut costs on average, around £0.15 per unit across Europe, with lower referral rates on cheap clothing, home goods, groceries, and pet products.

Real cost estimate: A £25 product sold through FBA typically loses £3.75 to £4 to the referral fee and £3 to £5 to fulfilment, so £7 to £9 before the cost of the goods, postage to the warehouse, or any advertising. Most sellers also spend 5 to 15% of revenue on Sponsored Products ads to stay visible. All-in, plan for Amazon taking 30 to 40% of your selling price on a typical FBA item.

What Works Well

✓ The customer base is the reason to be there. Amazon is the UK’s largest marketplace, and listing there puts your product where most product searches now start. No amount of marketing on your own site buys that footfall.

✓ FBA removes the shipping workload. Amazon stores, packs, delivers, and handles returns and customer messages. A one-person business can ship hundreds of orders a week without touching a parcel.

✓ The Prime badge sells. FBA listings qualify for Prime delivery, and Prime buyers filter for it. Sellers who switch a listing from FBM to FBA routinely see order volume rise on the same product at the same price.

✓ 2026 fees moved in the right direction. Average per-unit fees fell this year, with lower referral rates on low-priced items and cheaper fulfilment on parcels, which helps exactly the small sellers the old fee structure squeezed hardest.

Where It Falls Short

✗ The fee stack eats thin margins. Referral plus fulfilment plus storage plus ads can pass 40% of the sale price. Products with less than about 50% gross margin rarely survive it.

✗ Seller support is a known weak point. Account suspensions, hijacked listings, and stranded inventory get handled through slow, scripted case queues. Sellers with their whole income on Amazon carry real platform risk.

✗ Competition includes Amazon itself. If your product sells well, expect rivals on your listing, price wars for the Buy Box, and in some categories an Amazon own-brand version. You do not control the customer relationship or even the customer’s email address.

✗ Ads have shifted from optional to expected. Organic visibility for new listings is limited, so most launches now need Sponsored Products spend. That cost lands on top of every fee above.

Who Should Use Amazon

Amazon suits sellers with healthy margins, products that fit standard parcel sizes, and demand that already exists in search: think branded goods, private-label products with a clear angle, or resellers with sharp sourcing. It also fits businesses that want sales without building a store, since FBA plus the marketplace handles traffic, delivery, and returns in one place.

Who Should Look Elsewhere

If your margins are thin or your product is heavy, bulky, or slow-moving, the fees will bury you, and eBay, Etsy, or your own Shopify store keep more of each sale. If your brand depends on owning the customer relationship, Amazon works against that by design. And if your whole business would sit on one Amazon account, weigh the suspension risk before you commit stock to FBA warehouses.

Our Verdict

Selling on Amazon is a straight trade: the biggest audience in UK ecommerce in exchange for the biggest cut of your sale. FBA is genuinely excellent at logistics, the 2026 fee cuts helped, and for the right product the volume is life-changing. But Amazon controls the rules, the customer, and increasingly the ad tax you pay to be seen. Treat it as a powerful sales channel with a 30 to 40% cost of doing business, run the numbers per product before you list, and keep at least one other channel so a bad day in Seller Central cannot take your whole income with it.
