The independent company Book Tokens Ltd holds in reserve more funds than are required to redeem all un-used tokens which means there is always money to honour your Booksellers Token. Book Tokens are valid for two years from the date of purchase, so for eg. 24/12/2017 - 24/12/2019.
Please note, these are physical and not available to be emailed. Time Out Vouchers are available to be emailed. https://shop.timeout.co.nz/c/vouchers__37--2
