A great tip for finding an iPad 2!
So I ordered an ipad2 from apple because of coarse I couldn't find any in stores. After about two weeks I got tired of waiting and found this site whiling googling where to find iPads. I've seen some sites like this in these forums but have never seen this one which offers a lot more.
You can use it to see the inventory of every walmart, target, and best buy in your area. from what I have seen it is very accurate. After using this site four or five times throughout the day I found many iPads around me, but finally after only 2 days I found a black 32gig wifi, just what I wanted!
Good luck with your search!
