What makes this any different than walking into a Best Buy (or any other retail store for that matter) and buying a stereo (or TV, computer, etc) for $349 on Saturday and then going back on Sunday and seeing it marked down to $299? It happens all the time.
Apple has a price match/price guarantee policy just like most retailers do, but if you don't notice that it went on sale, then it's your loss if you don't go back in (or call) to get the difference refunded to you. 99% of stores aren't going to just give it to you out of the goodness of their hearts.
Geez, this is such a non issue it's not even funny...
