I have a friend who works for Target. Well, she actually has a "real" job but just works at Target 3-4 hours a week just to keep her discount.
Anyway, she gets a 15% discount on the iPhone(s)! Not only that but at Target you can actually RESERVE an iPhone.
Of course she tells me all this after I pre-order through AT&T
But that 15% discount ain't half bad.. For some reason I thought these 3rd party store employees (Target, Best Buy, etc.) couldn't get their discount on Apple products.
