EDIT: this deal is pretty borked. you're supposed to be able to pass on these codes to "all your friends". their FB page is full of complaints that nobody's code works and they've been false-starting this deal for like a week and canceling orders. doesn't really inspire a lot of confidence to order anything >.99 from them. i happened to stumble upon one that worked and placed an order (didn't work for a friend's subsequent order so don't bother asking). i was then given my own fresh referral code that didn't even work once for the friend either.
