Not trying to make anyone upset, but i can confirm that the sale is live in stores. I got Mass effect Trilogy and NFS Most wated Limited edition for $43.28 after taxes. Thanks OP!
If you go to the page of the promo, on the bottom says...
"The discount is valid until July 31, 2013. Amazon reserves the right to cancel it at any time."
Hitman absolution also $20. With 20% off if buy online.
The only problem is if best buy lower their price making buying there with the coupon cheaper...
Edit: They dont usually let you PM and use the coupon, they say your are double dipping.
