It's not too late to take advantage of the Barnes & Noble Groupon that I posted about on Friday. Also today you can get double back if you purchase your Groupon via Ebates. Just click on the Ebates link and search for Groupon and then get the Barnes & Noble deal. You'll pay $10 for $20 worth of products and also get 6% back!
(It's only .60 cents but using Ebates add up over time!) You will also get $5 if you are new to Ebates!
