It's going to be quite difficult for Amazon to price-match this deal from Best Buy and Barnes & Noble. You can pick up a new Barnes & Noble - 8GB NOOK HD Tablet for $149.99 (its best price ever by $50,) 16GB NOOK HD+ Tablet for $179.99 (its best by $90,) or a 32GB NOOK HD+ Tablet for just $199.99 ($100 of its lowest historical price.)
This killer deal comes in the wake of Barnes & Noble rolling out a new firmware for these devices that will turn them into full-fledged Android tablets. Yes, this includes gMail, the Play store, and all the other Google Apps. Concerns that this was too late a move to be competitive in a market flooded with the Nexus 7, Kindle Fire, and Ipad Mini might be moot now that even the best of these Nooks can be had for less than $200.
As our buddy, Kif, over at Gizmodo points out, this comes from straight the Barnes & Noble folks, so expect some other price-matching retailers to follow suit with this discount. It's only good to the 12th, though, so get on it now.
