The website calculates your voucher's value based on the amount paid for it, not its advertised value.
If your voucher was purchased as part of a special offer or had a discount applied, the value may not cover the full cost of a more expensive experience. In this case, you’ll need to pay the difference.
If your chosen experience costs less than your voucher’s value, the remaining amount will be converted into a credit voucher for future use on our voucher redemption website.
