How to Use Cashback Apps on Black Friday to Maximise Your Savings
Cashback works on Black Friday sale prices as well as full prices. If a retailer is listed on TopCashback or Quidco, you earn cashback on whatever price you pay — including discounted Black Friday prices. The mistake most people make is using a voucher code, which usually cancels the cashback.
The short answer
Summary
- Activate cashback before you click through to the retailer — not after you are already on the site
- Do not use voucher codes at checkout — most codes void cashback tracking entirely
- TopCashback and Quidco are the two main UK cashback sites and cover most major retailers
- Cashback credit cards can be stacked on top of cashback sites for an extra layer of return
- Cashback pays out weeks or months after purchase — it is a bonus, not an instant discount
The short answer
This guide is for information only and does not constitute financial advice. Always check your eligibility and read the full terms before applying for any financial product.
How does cashback work on Black Friday?
Cashback sites work by earning a commission from retailers when customers click through from their platform and make a purchase. They share a portion of that commission with you as cashback.
The retailer does not change their price — the cashback comes from the commission the retailer pays to the cashback site. This means it stacks on top of whatever price you pay, including Black Friday sale prices.
Example: A TV normally costs £800. It is £560 on Black Friday (30% off). TopCashback offers 2% cashback at that retailer. You click through via TopCashback, pay £560, and earn £11.20 cashback on top of the saving. Your effective cost is £548.80.
Which cashback sites work on Black Friday?
The two main UK cashback sites are TopCashback and Quidco. Both cover hundreds of retailers and both work during Black Friday sales.
| Feature | TopCashback | Quidco |
|---|---|---|
| Membership fee | Free (Plus tier is paid) | Free (Premium tier is paid) |
| Retailer coverage | 4,000+ | 4,000+ |
| Average cashback rate | Slightly higher | Slightly lower |
| Payout method | Bank transfer, PayPal, gift cards | Bank transfer, PayPal, gift cards |
| Minimum withdrawal | No minimum (bank transfer) | £1 (bank transfer) |
| Black Friday rates | Often boosted | Often boosted |
It is worth checking both sites before each purchase — the rates differ by retailer and change frequently. Both offer higher rates during Black Friday, often advertised as "boosted cashback" events.
For grocery cashback apps like Shopmium and GreenJinn, these work on supermarket purchases and can be used for Christmas food shopping rather than Black Friday electronics, but the principle is the same: activate before you shop.

How do you activate cashback correctly?
The process is the same on both TopCashback and Quidco:
- Go to the cashback site first — log in to your TopCashback or Quidco account
- Search for the retailer you want to buy from
- Click the "Get cashback" or "Shop now" button on the cashback site — this sets the tracking cookie
- Complete your purchase normally on the retailer's website without leaving that browser session
- Do not apply voucher codes (see below)
- Wait for the cashback to track — usually within 24-48 hours, it appears as "pending" in your cashback account
Key rule: the click-through must happen in the same browser session as the purchase. If you close the browser, switch devices, or navigate away and return directly to the retailer, the tracking cookie is usually lost.
Why do voucher codes cancel cashback?
This is the most common mistake. Most cashback terms explicitly state that using a promotional code or voucher code at checkout voids the cashback.
The reason: retailers pay commission only on purchases made through the cashback platform's tracked link. When a voucher code is applied, the retailer's system often attributes the sale to a different marketing channel (the voucher code provider), and the cashback site's tracking is overridden.
What you can do instead:
- Look for cashback deals that include their own discount (some cashback offers include a boosted rate that effectively functions as a discount)
- Accept the sale price without an additional code and take the cashback
- Compare: does the voucher code save more than the cashback? Use whichever is better — just not both
Can you stack a cashback credit card on top of a cashback site?
Yes — this is the most effective combination if you have a cashback credit card and pay it off in full each month.
The order:
- Click through from TopCashback or Quidco (activates site cashback)
- Pay using your cashback credit card (adds card cashback)
- No voucher codes
- Pay the credit card balance in full before the statement date
If you do not pay the balance in full, the interest charged will exceed the cashback earned. This combination only works as a saving if you are not carrying a balance.
What cashback rates can you expect on Black Friday?
Rates vary by retailer and change throughout the sales period. During Black Friday, many cashback sites run boosted promotions. Typical ranges:
| Retailer type | Typical cashback rate | Black Friday rate (approximate) |
|---|---|---|
| Electronics and appliances | 1-3% | 2-5% (varies) |
| Fashion and clothing | 3-8% | 5-12% |
| Home and garden | 2-6% | 4-8% |
| Travel (hotels, flights) | 3-10% | Standard rates usually |
| Supermarkets | 0.5-2% | Standard rates usually |
Check the cashback site on the day — rates are updated in real time and Black Friday boosted rates are often only live for 24-48 hours.
FAQ
How long does it take for Black Friday cashback to pay out? Most cashback appears as "pending" within 24-72 hours of purchase. It then goes through a confirmation period — typically 30-90 days — during which the retailer confirms the sale has not been returned. After confirmation it moves to "payable" and you can withdraw. Some retailers have longer confirmation periods; this is disclosed on the cashback site listing.
What happens if I return a Black Friday purchase — do I keep the cashback? No. If you return an item, the retailer claws back the commission, and the cashback site removes the cashback from your account. If the cashback has already been paid out, it may be deducted from future earnings.
Can I use cashback sites on mobile apps? Yes, but you need to click through from the cashback site's mobile browser — not from the retailer's app. Purchases made in a retailer's app without click-through tracking do not qualify for cashback. Some cashback sites have their own app that handles this.
Is it safe to use TopCashback and Quidco? Both are established UK businesses with millions of members. They do not store your payment details — you pay the retailer directly. The tracking is done via cookies, which is standard e-commerce practice.
Can I use cashback on Black Friday marketplace sellers (Amazon third-party, eBay)? Cashback on Amazon applies to Amazon's own stock, not to third-party marketplace sellers. eBay cashback typically applies to eligible fixed-price listings, not auctions. Check the terms on the cashback site for each retailer.
