Where to source products to resell

Sourcing is the whole game. Anyone can list an item, but the money is made the moment you buy. Buy well and the sale takes care of itself. Buy badly and no amount of clever photography saves you.

Here’s where UK resellers actually find stock, and how to know it’s worth buying before you commit.

The main sourcing routes

Charity shops

Still the classic starting point, and still worth it if you’re patient. Charity shops in wealthier areas and near universities tend to have better stock. Prices vary wildly from shop to shop, and staff knowledge varies too, which is exactly where the deals hide. Go often, be friendly, and learn which shops price low.

Car boot sales

Early mornings, cash in your pocket, and sellers who want everything gone by lunchtime. Car boots are brilliant for branded clothing, vintage, homeware and random collectibles. Haggling is expected. Turn up early for the best pick or late for desperate discounts.

Wholesale and liquidation

Buying in bulk changes the game once you know what sells. Liquidation pallets and clearance lots from retailers can be cheap per unit, but they’re a gamble: you might get returns, damaged goods, or stuff nobody wants mixed in with the good bits. Start with small lots from a reputable UK supplier before you spend hundreds on a pallet.

Online arbitrage

Buying from one online shop to sell on another. Clearance sections, flash sales, mispriced listings, and end-of-line stock all work. The advantage is you can do it from your sofa. The catch is that everyone else can too, so margins get competitive fast. Speed and knowing your numbers win here.

Clearance and end-of-line

Supermarkets, high-street shops and outlet stores all clear seasonal and discontinued stock. Yellow-sticker reductions, sale rails and “last few” bins can hide items that resell for full price or more, especially discontinued colours and sizes.

Auctions and house clearances

Local auction houses and general sale rooms are underused by beginners. You can buy job lots cheaply, particularly homeware, tools, books and collectibles. House clearances (yours or a friend’s, or ones advertised locally) can turn up genuine treasure. Just be ready to sort, clean and store what you buy.

Your own wardrobe

The cheapest stock you’ll ever own is the stuff already in your house. Clothes you don’t wear, gadgets in a drawer, books on a shelf. It costs you nothing, it teaches you how listing and posting works, and it clears space. Almost every reseller started here.

Check the profit before you buy

This is the habit that separates people who make money from people who just move it around. Before you hand over any cash, run the numbers in your head (or on your phone).

The simple version:

Sold price − (buy price + fees + postage + packaging) = your profit

Work through it every time:

• Sold price: what it actually sold for recently, from completed listings, not the hopeful asking prices.
• Buy price: what you’re about to pay, including any petrol or entry fee if you want to be honest with yourself.
• Selling fees: whatever the platform takes. On some it’s the buyer who pays the protection fee, on others it comes off your end. Know which is which.
• Postage: the real cost for the size and weight, not a guess. Bulky and heavy items eat profit.
• Packaging: bags, boxes, tape, labels. Small per item, but it adds up.

If the gap is thin, walk away. A £3 profit that takes you twenty minutes to list and pack and a trip to the post office isn’t really £3.

A rule of thumb many resellers use: aim to at least double your money after all costs on lower-value items, because that cushion absorbs the returns, the duds and the ones that sit unsold.

Keeping a running record of what you paid versus what you actually cleared, per item, is how you learn which sourcing routes are worth your time. logs your buy price, fees and postage against each sale so your true margin is sitting there in black and white, not a rough feeling in your head.

Source in a couple of ways you enjoy, learn your numbers cold, and the good buys start to jump out at you.
