I suppose it's a sign of our evolution to an internet controlled marketing system.
Regarding Best Buy, I have totally crossed them off my list of stores to consider when I am shopping for something, because of their policy of bait and switch. Several times I have rushed down to take advantage of a great bargain they advertise, and when I get there it's always the same story: "Oh they were gone in ten minutes, let me show you this . . ."
No thanks,
