The biggest savings rarely come from one lever. A 10% code is good; a 10% code plus cashback on the discounted total is better. Here's how stacking works, and where people get it wrong.
The right order
- Start from the store page on Vouchernaut — cashback only tracks when the visit goes through our disclosed link, so click out first.
- Apply the voucher code at checkout — the discount comes off your basket immediately.
- Cashback is then calculated on what you actually paid — the discounted, post-code total (usually excluding VAT and delivery).
Doing it the other way round — finding a code on some other tab after you've clicked through — is the classic way to void your own cashback. Some coupon tools quietly overwrite the tracking as you check out; we explain why we don't in what "disclosed cashback" means.
When stacking is allowed
Not every offer stacks, and the offer card tells you. As a rule of thumb:
- Sitewide percentage codes + cashback — usually fine.
- Member-only codes (NHS, student, forces) + cashback — usually fine, and often the deepest combined saving on the site.
- "No further discounts" sale items — the code may be rejected at checkout, but cashback generally still tracks.
Watch the exclusions
Cashback rates commonly exclude gift cards, and some categories track at a lower rate. The store page lists the live rate and any exclusions before you click out — read it once and you won't be surprised at confirmation time.
If something doesn't track
Orders normally appear in your wallet within a couple of days as pending, then confirm after the retailer's return window. If a purchase never shows up, file a missing-cashback claim from the wallet and we'll chase it.
Stacked properly, a good code plus cashback routinely beats any single "mega deal" — and every part of it is disclosed up front.
