They sell some crazy T-Shirts. You make $4 a sale.
They don't have any full page ads, but if you want to use one I'm sure you could just do a variation on the layout of their main page on your own site. You can link to any page of their site with your own referral code, so if you want to link to specific shirt designs, you can.
