$20 Barnes and Noble credit for $10 still available!

I'm re-posting this because I can't believe it's still available. Click here to go to Groupon's website where you can buy a $20 credit to Barnes and Noble for just $10. If you don't see it on your Groupon page check where it says "More Great Deals Nearby" to the right of the main deal.  Please note if you bought this earlier in the week you will not be eligible to buy it again.
