I've purchased Prize Claim Tickets, but I can't use them.

Make sure that you have activated the Prize Claim Tickets in your NC inventory. Once you have activated your Prize Claim Tickets, visit the Stocking Stufftacular page. Click on a missing stocking to use the Missed Day Prize Claim Ticket or click on a full stocking to use the Extra Prize Claim Ticket. Remember, once your ticket is used, it cannot be undone!
