This sale has been on Ebay since yesterday morning, and I'm surprised it hasn't popped up on any blogs yet.
It looks like B&N decided to start clearing out the Nook Touch refurbs the same week that they shipped the new Nook Glow because it's on sale right now on Ebay. Barnes & Noble has it marked down to $59, which is $20 off their regular price for the refurb.
Given the large hacking community surrounding this ereader, the Nook Touch is definitely worth looking at when thinking about getting a tablet. I have one, and I keep planning to apply the hacks.
In fact, I've come to think that a hacked Nook Touch is a better Android tablet than my hacked Sony Reader Wifi. I spent part of last weekend reviewing the latest tricks for hacking the Sony Reader Wifi and it was a little disappointing that the one biggest issue, namely lack of space to install apps, still was intractable to simple hacking. There is a solution but ut would require unhacking my Sony Reader Wifi, updating it, and then hacking it again (twice). I'm not sure it's worth the effort, given that I have other gadges to play with.
