Was looking to get a different color iPhone as an exchange, went in, asked them if they had stock, they said they did, I say I want to exchange for a different color and show them my online receipt. The guy says they can't accept a exchange for an online order, and that I would have to return to the online store and buy it again if they have stock. Same thing for anything else purchased online. I found it odd as I wasn't doing a return, just an exchange for something that is the same price... I'm pretty surprised and I feel like that this isn't the case. Any Apple reps here who can clarify?
