It's not getting much press today but Barnes & Noble just sent out a press release announcing a sale. As of this morning B&N put the Nook Touch on sale for $80. This is for the new unit, not refurbished, and you can find it both on their website and in stores.
You can also find it on sale at a number of US retailers. So I guess that means the Mother's Day sale I noted yesterday was part of a marketing push which got caught up in the Nook Spinoff news. The Nook Color is also on sale at B&N and Staples.
