Actually, according to Best Buy's online weekly ad, this price is good Nov 20 - 23. However, I don't know if the supply will last that long.
The ad is here (fingers crossed that this doesn't have any hidden affiliate links):
I just bought two for gifts this afternoon on my way home from work: U.S. Pacific time, 11/21. (Yeah, I'm cheap - they can deal with the special offers
) Although there were no lines, and just a couple of other folks looking at them, the salesman told me they'd been selling like crazy, and his store didn't have many left. So, I suspect there won't be any left by Nov 23, unless they get more stock in the meantime.
This is only $5 more than the rumoured Target doorbuster Black Friday price, and I will happily pay $5 to not have to stand around at midnight for a chance to maybe buy one. Not that I was going to anyway!
Anyway, it appears there might be a bit more time to buy, but I'd call ahead and check for stock (or maybe check online) before making any special trips...
