There are several places in NYC to buy Junk Food T-Shirts. To be simple Urban Outfitters has some of them. There are several smaller shops as well like YRB. Junk Food itself doesnt sell their tees on their website as far as I know but if you can wait until the next day, then is probably the next best thing to an actual Junk Food T-Shirt store. They have the biggest selection of Junk Food Tees by far and they ship next day.
