Best Buy exchange

[pappy53]

About 10 days ago, I did a Verizon upgrade with Best Buy, getting a Galaxy S3. I didn't really like the S3 enough to keep it, so I went back and exchanged it for an iPhone 5. I really like the iPhone, but I guess that I am "Android to the bone", as I keep coming back to it! My question is, does Best Buy limit you to one exchange during their 15-day return policy (which used to be 30 days)? I think that I would like a Razr Maxx HD. If I can't exchange it, then I guess that I can refund it and get something else. I am asking on here because BB is now closed, and I had it on my mind. TIA!
