Refurbished Nook Tablet 16GB Spotted Online for $140
Even more so if you're willing to roll the dice with a refurbished unit. Case in point, Overstock.com is now selling a refurbished 16GB Nook Tablet for just $140. That's $39 off the retail price for a new model (minus $2.95 for shipping), and it still comes with a 1-year warranty from B&N.
If every penny counts, Overstock is also selling the 8GB model for $135 (also refurbished), which is a deal in and of itself, though it's not a great buy when $5 extra nets you double the storage space.
The Nook Tablet runs a custom version of Android 2.3 (Gingerbread), though just like the Kindle Fire, it's possible to root the device and install a clean build.
