Alright guys, I've got a helluva idea. We use the product locator to find the stores that have the guides. Now, this is only updated once a night around midnight, but it will at least give us a chance to find the items. The only problem is that we need all the SKUs. I've got all the ones from what I've listed today, so I'll go ahead and start this.
Basically, copy this link into your browser bar.
www . gamestop.com/productavail.asp?miles=100&sku=YYYYYY&zip=XXXXX&pr oduct_name=20GB+PS3+%2D+Used&platforms=PS3&sbox%20 =160726a%2Ejpg&status=BO&bn=False
Take away the spaces at the begining, change the zip to equal your zip code, and then put in whatever SKU you're looking for.

Now, as long as the store HASN'T run the guides out of their inventory, this should be accurate. When I personally get the drops, I take care of them as soon as possible, but I know some other stores in the area don't even care.
And remember, tonight most stores will show in stock of the items; the real test will be if they show tomorrow morning.
