The Margin Most Resellers Leave on the Table
When resellers think about improving their margins, they usually focus on two things: finding cheaper stock and selling for higher prices. Both matter, but there's a third lever that most people completely ignore — reducing what you pay on purchases you're already making.
If you're buying stock from online retailers — whether that's restocks on Amazon, clearance from Argos, new releases from Pokémon Center, or anything else — you're probably paying full price every time. Cashback sites like TopCashback let you earn a percentage back on those purchases with zero extra effort. It's not life-changing money on a single transaction, but across hundreds of purchases a year, it adds up to a meaningful chunk of extra profit.
This guide explains how it works and how to set it up properly so you never miss cashback on a stock purchase again.
What Is TopCashback?
TopCashback is a UK-based cashback platform that partners with thousands of online retailers. When you buy something through their tracking link, the retailer pays TopCashback a referral commission — and TopCashback passes most of that commission back to you as cashback.
You're not paying more for the product. The retailer price is exactly the same. You're just getting a cut of the marketing fee that the retailer would have paid anyway.
It's completely free to use. No subscription, no hidden fees, no catch. The cashback rates vary by retailer — typically between 1% and 15%, sometimes higher during promotional periods.
How to Set It Up (5 Minutes)
Step 1: Create Your Account
Sign up for a free TopCashback account at topcashback.co.uk. Registration takes about two minutes — just an email, password, and payment preference.
Step 2: Install the Browser Extension
This is the step that makes the whole system effortless. Install the TopCashback Chrome Extension — it automatically detects when you're on a partner retailer's website and pops up a notification reminding you to activate cashback before you check out.
Without the extension, you'd need to remember to visit TopCashback's website first and click through to the retailer every time. With the extension, it happens in the background. Install it once and forget about it — it'll remind you when cashback is available.
Step 3: Activate Before You Buy
When you spot a restock or are about to purchase stock from any online retailer, click the TopCashback extension icon or notification to activate the cashback tracking. Then complete your purchase in the same browsing session. That's it.
How the Money Works
After you make a qualifying purchase, the cashback typically appears in your TopCashback account within a few hours to a few days. It'll show as "Pending" initially — this is normal. It moves to "Payable" once the retailer confirms the transaction, which usually takes 30–90 days depending on the retailer's return window.
Once it's payable, you can cash out via:
- PayPal — fastest option, usually arrives same day
- Direct bank transfer — takes a couple of business days
- Gift cards — sometimes available at a bonus rate (e.g., get £52 in Amazon credit for £50 in cashback)
Why This Matters for Resellers Specifically
Casual shoppers might earn £20–30 a year from cashback on the odd online purchase. Resellers spend significantly more online — you're buying stock regularly from multiple retailers. That changes the maths completely.
Consider this: if you spend £500 a month on stock from online retailers and average even 3% cashback, that's £15 a month or £180 a year in pure extra profit. At 5% average cashback (achievable during promotional periods), that's £300 a year. And this is money you earn on purchases you were going to make anyway.
Maximising Your Cashback
Stack With Other Savings
Cashback stacks with discount codes, sale prices, and vouchers. If a retailer is running a 20% off sale and also offers 5% cashback through TopCashback, you get both. Always check for available cashback before completing any stock purchase.
Check Rates Before Choosing a Retailer
If you can source the same product from multiple retailers, compare their cashback rates. A product that costs £40 at Retailer A with 2% cashback and £40 at Retailer B with 8% cashback means Retailer B saves you an extra £2.40. On a single item that's trivial, but across 50+ purchases it becomes significant.
Watch for Elevated Rates
TopCashback regularly runs promotional periods where specific retailers offer boosted cashback rates — sometimes double or triple the normal amount. If you can time non-urgent stock purchases to coincide with these promotions, you'll earn considerably more.
Combine With Credit Card Rewards
If you're using a rewards credit card (like Amex or Capital On Tap) for your stock purchases, you're earning card points on top of your cashback. Those points can then be converted into cash through services like WeBuyMiles — effectively giving you a third layer of return on every purchase. We covered this in more detail in our credit card points guide.
Common Questions
Does it work on Amazon?
TopCashback does partner with Amazon, but availability and rates vary. Amazon cashback tends to be category-specific and often lower than other retailers. It's worth checking each time, but don't count on it for every Amazon purchase.
What if my cashback doesn't track?
It happens occasionally. If you made a purchase through TopCashback and the cashback doesn't appear within a few days, submit a "Missing Cashback" claim through your account. You'll need your order confirmation as proof. Most claims get resolved successfully — just make sure you activated cashback in the same browser session as your purchase.
Is it actually worth the effort?
Once the browser extension is installed, there is no effort. It takes one click to activate cashback before a purchase. The question isn't whether it's worth it — it's why you'd choose not to do it when it costs you nothing and returns money on every qualifying purchase.
Getting Started
The setup is genuinely a five-minute job: create a free account, install the Chrome extension, and activate cashback before your next stock purchase. That's the entire process. From that point on, you'll earn money back on purchases you were making anyway.
It's one of those tools that costs nothing and only adds to your bottom line — similar to using real-time alerts to find profitable stock before other sellers. Small edges compound over time, and the resellers who consistently make good money are the ones who stack every advantage available to them.
