Why voucher codes don't work (and how to avoid it)
By ClickAndPerk · updated 7 November 2026
Most failed codes come down to the small print.
- Expired: many codes run for a few days only. We mark codes expired as soon as we see they've stopped.
- Exclusions: sale items, gift cards and some brands are often excluded.
- Minimum spend: the basket may need to reach a set total before delivery.
- New customers only: some codes only work on a first order.
- One code per order: most shops don't let you combine codes.
Tip: add items to your basket first, then try the code before you enter payment details.
