It would be very helpful if the gift voucher code used for a purchase was displayed on the sales receipt. We had an issue where a dad was querying the use of a gift voucher. It looks like his son used it, but we can't prove if that exact gift voucher was used because the code doesn't show on the sales receipt. And I can't find it linked to the transaction anywhere else. I have found the date it was redeemed, but it doesn't definitively link it to that transaction.
I might be missing something, but this would be uselful.
Thanks :)
