How Do Cashback Sites Actually Work?
Cashback sites operate on a simple principle: when you click through to a retailer via the cashback platform and make a purchase, the retailer pays the cashback site a referral commission. The cashback site then shares a portion of that commission with you.
It costs the retailer nothing extra — they'd be paying that commission to an affiliate regardless. You simply need to remember to start your shopping journey via the cashback site rather than going directly to the retailer.
Key Things to Look for in a Cashback Site
- Retailer coverage: Does the site have partnerships with the shops you already use?
- Cashback rates: Rates vary significantly between platforms — even for the same retailer.
- Payment methods: Can you withdraw to a bank account, PayPal, or only gift cards?
- Minimum withdrawal: Some platforms require a minimum balance before you can cash out.
- Tracking reliability: Look for platforms with transparent tracking and a clear dispute process.
- Speed of payment: Some retailers have 90-day+ confirmation windows before cashback is released.
Types of Cashback Offers
Not all cashback is straightforward. Here are the main types you'll encounter:
- Percentage cashback: A fixed percentage of your purchase value (e.g. 5% back on clothing).
- Fixed cashback: A flat amount for completing an action (e.g. £15 for signing up to a broadband deal).
- Tiered cashback: Higher rates unlock when you spend above a threshold.
- Upsized/bonus cashback: Temporary rate boosts — often featured on the platform's homepage.
Common Mistakes That Cost You Cashback
- Using a voucher code not listed on the cashback site — can void your cashback with some retailers.
- Clicking through then opening a new tab — breaks the tracking cookie.
- Using an ad blocker — can prevent the tracking script from firing.
- Returning items partially — cashback is usually adjusted or cancelled on returned goods.
- Not being logged in to the cashback site before clicking through.
Loyalty Points vs. Cashback: Which Is Better?
| Factor | Cashback | Loyalty Points |
|---|---|---|
| Flexibility | High — spend anywhere | Low — tied to one brand |
| Value clarity | Clear monetary value | Can be complex to calculate |
| Expiry risk | Usually low | Points can expire unused |
| Maximum value | Moderate | High if used on rewards strategically |
Getting Started
The simplest way to start earning cashback is to sign up to one or two established platforms, install their browser extension as a reminder, and make a habit of clicking through before any online purchase. Over a year of regular shopping, even a modest cashback rate can add up to a meaningful sum — without changing what you buy or where you buy it.
