Take a look at the order guide and then click on the PayPal "BuyNow" Button at the top left (right above the head of the roaring grizzly graphic!). There are two PayPal "BuyNow" Buttons -- one is just for tshirts and it includes all three of the tshirt designs with the option to choose sizes (XS, S, M, L, XL, 2XL) at the "American Apparel" Tshirt price and also to choose the same at the Value Tshirt (Valu T) and various sizes. The other one is for all of the non-Tee merchandise (travel mug, autograph posters, key chain, notecard, etc.). If you have any questions, send me an email at firstname.lastname@example.org. Cheers!
