Where to buy the Nook

On my search for the most cost effective tablet/e-reader, I found the Nook. You can buy the Nook at Best Buy, Barnes & Noble, Office Max, Office Depot, Walmart and of course, online. The best thing about the Nook (aside from the ability to hack the tablet) is that Barnes & Nobles has more than 2 million books. It can also access the Amazon Kindle market.
