I got mine in the mail today you get six stickers on a postcard sized letternow i need to find out where to put them.
There is no purchase necessary. PETA is a non-profit.
Simple form. Put info in and hit submit got this message: "You should receive your sticker pack in the next three to four weeks, so be on the lookout. Didn't see anywhere that mentioned a purchase...
This seems to only be available with a purchase.
