Question to all you Nexus 7 owners/pre-orders

Amongst the confusion and the rather large amount of upset customers I've seen, I decided I would like to actually see the Nexus 7 with my own eyes before I purchase it. I'm pretty sure I will get it regardless but walking into a store and leaving with it is much more welcoming to me then the waiting game I've been hearing about when ordering online. My question is though, how long do you all think B&M stores will have the tablet on the shelves for sale? I went into Gamestop today and the guy said only pre-orders were getting their tabs. He also said that they were on Wave 3 and it may be August until I could get one. So is my best bet is to go ahead and give Google Play a try? I suppose I can mess around with my newly updated Epic 4G Touch until then ^.^
