This is a nice new feature, thanks for pointing it out OP.
However, the problem I have with this is, it tells you which stores in your area carry the game, however the game prices are not the same as those cited on EBgames.com.
Case in point, TMNT lists onsite as $4.99 but at the stores it's still $9.99, same for Indiana Jones and the Emperor's Tomb.
On the other hand, the Jewel case games like the Lego Creator, Lego Island 2 etc. are shown as $2.99 to 1.99 but the stores are clearing those out for 25 cents.
(additional update - I did a search for TMNT and the store availability showed it at several stores. I did a call in to check on the price and confirm availability and both were wrong as far as what the website says vs. reality. None of the stores had the game in stock and their price for the game was higher that that posted on the website - website $4.99 and B&M $14.99).
