"What if I want to order some stuff using
a check and snail mail?"

Just go to the website, go through all the process of ordering what you want until you get to the final total with taxes and shipping (the same page where it asks for a credit card number). Then just print out that page and send it in with a check for the appropriate amount. If you don't have a printer handy, just copy down all that info on a piece of paper.

Send it "Attention: Gift Shop Orders" to the address below (don't address it to me personally as that will cause a delay).
