There is a shipping thread at the top of the page, try there for your basic package needs.
If NFL.com uses FedEx like NHL.com does, there could be a big delay. Took me 3 weeks to get a sweatshirt at Christmas. Of course that's a busy period however my point is the same. If there is a window of shipping time offered, unless it guaranteed, good luck to you. The hotel will hold it for about a week prior BUT if the package is late you might have to go home without it. Just a heads up.
