Back when iTunes was new, a potato chip company in NZ had a promotion where each packet of chips had a printed code that got you enough iTunes credit to buy one song. By itself it was a good deal - buy a packet of chips for $1.50 (or whatever) and get a song worth 99 cents for free. What made it amazing was I found that the codes were also printed in the smaller kids-lunch-sized packets that the local discount supermarket was selling in packs of 8 for $6. Not the most spectacular discount but I still felt I was sticking it to the man each time I ate a tiny packet of chips while listening to a new song.
