The gift card is for Barnes and Noble’s retail stores and their online store and can even be used to purchase ebooks, e-magazines, and newspapers for the Nook.
The Nook sells for $259 from both stores and comes with free shipping.
I noticed that the Nook is highly rated at Best Buy, with 4.7 stars over 52 reviews. I wouldn’t go that high; more like a solid 4 now with the firmware upgrades. Here’s my detailed review of the Nook, if the deal has you curious about it.
