a few years ago there was a local promotion for packs of nestea, where each case contained a coupon for a free case of ice tea. The coupon didn't say you couldn't redeem it for the same box (which contained another coupon) A bunch of people (me included) went around and basically cleaned out all the stores that sold it. There was a hilarious thread on red flag deals where people posted pictures of SUVs packed to the brim with ice tea.
