What's far more common would be more or less uninformed people walked in to buy an iphone 5, and were told it was out of stock for weeks and the salesman (who gets a significantly better commission on Samsung phones) tries his best to sell them the GS3 and sometimes does. I know this is a common story because I've actually seen the exact scenario play out several times in the course of an hour I spent with my wife in the Sprint store activating her phone.
