I wasn't planning to do another BFS post, but one of my readers pointed out that B&N are selling refurbished Nook Wifi ereaders for $79. You can find them on Ebay, and they come with the standard 1 year warranty.
I think I'm seeing a pattern here.
The Nook shows up in a Best Buy advert for $99. Amazon responded by offering refurbished K2 ereaders (tomorrow) for $89. B&N shoots back with the $79 Nook Wifi (they only started selling it 3 hours ago).
I was about to call this as the best Black Friday sale, but now I would bet dollars to donuts that Amazon will announce a better sale some time today.
Let's see what happens.
