Payment is strictly contactless via PayNow or PayLah! only.
You can also pay for your purchases at Thryft Book Fair using any existing Thryft credits. Simply bring along the email with the gift-card that you received from your previous trade-in, and show us the QR code/gift code during payment. If you do not have enough on your gift card to pay for your entire purchase, you can use PayNow or PayLah! to top up for the balance.
