Big box stores give gift cards in return for falsely returned items (get a receipt, walk out with the same thing twice; this is why the guy at the door wants to mark your receipt with a market.) So of COURSE people are willing to take a lower price for their $100 gift cards - they paid less than $100. My theory is that the gift card economy is a shadow economy for people who need to use plastic for whatever reason but are unable to open accounts (lack of documentation I guess?)
