I am flying up to Portland, OR and trying to get a decent amount of iPhones from Apple store. I heard that Apple change their store policy to 5 iPhones per cusomter. Also, are they still tracking your credit card once you bought 5 iPhones? Because my co-worker told me that he bought like 20 iPhones in 4 Apple stores with same credit card. No questions asked! What is the strategy for getting lot of iPhones?
