Make sure that you have entered the voucher code with no extra spaces or punctuation. Bear in mind that coupon codes and offers can expire, and sometimes coupon codes can't be cumulated with other offers, so make sure that all the coupon conditions are met when applying the coupon.
Here are some common error messages, explained:
“Coupon has expired”: Your coupon is out of date and cannot be applied
“Coupon does not exist”: You have entered an invalid coupon
“Another coupon is already in use, and cannot be combined with this coupon”: You cannot combine these two offers with each other.
