How does retail arbitrage work in the UK?

Retail arbitrage (RA) is the oldest way into Amazon FBA. You walk a shop, find a product that sells on Amazon for more than the shelf price, buy it, and send it to an Amazon warehouse to be sold. The idea is simple. The difficulty is knowing in seconds whether a product really makes money once every cost is counted.

How it works step by step

(1) Find a product in a UK shop, usually on clearance, a promotion or a price mistake. (2) Scan its barcode with a seller app to see the Amazon price, sales rank and fees. (3) Work out profit after the shelf price, Amazon referral and FBA fees, and VAT. (4) Buy only what clears your minimum profit and return on investment. (5) Prep the items, create a shipment and send them to FBA. (6) Once they sell, Amazon pays you out and you start again.

Where UK sellers source

Typical hunting grounds are UK retailers such as Argos, Boots, Tesco, ASDA, B&M, The Range and Wickes, plus supermarkets and discount stores. Deals tend to be local and short-lived: a clearance line is gone when the stock is. That is why many sellers pair their own shop visits with a community that shares leads and alerts.

The costs people forget

Profit on the screen is not profit in the bank. Count Amazon fees and the VAT on them, your travel and time, prep supplies, inbound shipping to the warehouse if it is not free, and returns. If you are VAT-registered you need proper VAT receipts to reclaim the VAT on what you buy; if you are not, that VAT is simply part of your cost. Get your VAT position straight before you scale.

Gating and restrictions

Many good-looking products are restricted: some brands and categories need Amazon's approval before you can sell them. Check the product is open to your account before you buy, not after. Our ungating guide explains how approval works.

Is retail arbitrage still worth doing?

It can be, but it is time-heavy and the finds are inconsistent, which is why many UK sellers add online arbitrage, where you source from retailer websites without leaving the house, and later wholesale for repeatable stock. A sensible start is a small first batch of low-cost, ungated products to learn the process before you commit real money.
