Well, not exactly, but when I went in to buy an iPhone 5 case, the employee asked if I had the Apple Store app on my iPhone. Since I did, he walked me through making a self purchase. Scan the bar code and sign in with Apple ID and you're good to go. I guess the idea is that you go in, make your purchase and walk out with the item. Pretty awesome. I guess there are so many eyes on you in that store, that they aren't worried about theft.
