*shrug* Why make a trip all the way over there if there's no guarantee they have one? I looked on their site and only found one *not in stores* that fits only 12 cases.
You think Walmart would have more of a selection than that. You could try and call them, maybe they have some other ones in stock. Good luck in you hunt.
I abhor walmart.com. Not only does their search engine fail 90% of the time, but now they're offering products sold by 3rd party sellers through their website???
Anyway, if this doesn't work, OP, I found this information for you as well: 360 game cases are shaped exactly like something else called a Digital Versatile Disc, which is supposedly rather common nowadays and easy to find stands for. Big Lots has great ones that are cheap.
Awesome... I didn't see that one on the site (probably due to a bad search engine like you said). I'll inquire with them about the item and see if walmart sells it in stores. It does look kinda .. flimsy? though.
