Gift Vouchers

Traditional gift vouchers are printed paper gifts available in set values that can be spent in specific stores. Open-loop, semi-open loop, and closed-loop are often terms used when referring to gift vouchers. All gift cards sold via our partners’ websites are closed loop. This means that the gift card can only be spent at a single brand location, for example, an Xbox voucher can only be spent at Xbox etc.
