Do an Apple store online purchase with in-store pickup. I just did it last night using the iPhone Apple store app. It allows you to choose any apple store for pickup and it shows availability at that store. My closest one had none but the next closest did. I got there today and they had none on the wall but they did have the online purchase/pickup units in the back. Apparently that stock is just for online orders. You can't just check availability, you have to complete the purchase.
