One of those 'Share on Facebook' deals.
Expires 6/23, just in time to get a $30 Wolfenstien with the sale coming up.
Works online. Cannot be used on 'Video game Hardware'.
Edit: Coupon says it's good at Sears too.
Edit 2: For those who do not understand how these deals work, the will send a message to the 3 friends you select and will have access to your info; much like Farmville or any other Facebook game/app.
If you are not confortable with that, then don't to the deal and always read the fine print.
