The order that works
- Add everything to the basket first. Changing the basket after applying a card sometimes releases the card and sometimes does not.
- Apply the promo or discount code. This changes the price. Do it before anything pays the bill.
- Apply the gift card. It covers what it can.
- Pay the remainder with a bank card.
The reason for that order is simple: a discount reduces the total, and you want the gift card spent against the reduced total, not the original one. Apply the gift card first at a checkout that recalculates badly and you can end up with the discount coming off the part you were paying by card — leaving more of the gift balance used than necessary.
When the checkout only takes one payment method
Some smaller shops genuinely cannot split. Two workarounds:
- Load the gift balance onto your account first, where the brand supports it. Then it is not a second payment method, it is your balance.
- Split the order into two. Awkward, sometimes costs a second delivery charge, but it works.
Multiple gift cards on one order
Usually allowed, often capped — two or three is a common limit. If you have four small balances, consolidate onto an account balance where you can.
What to check before you confirm
- The discount is still showing.
- The gift card amount applied is what you expected.
- The remainder on the bank card matches the difference.
That check takes five seconds and catches the checkout quirks that are genuinely hard to unpick afterwards.
Refunds after a split payment
This is where it gets messy, and it is worth knowing in advance: a refund usually goes back proportionally, meaning part to the bank card and part to a new gift card — not the original one, which may no longer exist.
So a £60 order paid with £40 gift and £20 card, refunded in full, typically returns £20 to the bank and £40 as a fresh gift card. Plan around that before using a gift card on something you might return. There is more in returns and refunds when you paid with a gift card.
