> dynamic pricing This is one of the (growing) reasons I dislike Amazon. Several times I've found a decent deal that I know a friend or family member would like - sent it to them, only for them to discover (sometimes just minutes later) that the deal has suddenly vanished. On the face of it, Amazon is doing this as a simple function of supply/demand, though it sure could be construed as form of bait-and-switch pricing!
