Not sure if this is common knowledge, but apparently if you buy something on Amazon and for some reason the price drops before it gets delivered, and you try to cancel the order and place another one at the dropped price, you get an option to get the price difference as an Amazon gift card. So yeh, putting it out for anyone out there.
