Hey everyone! I was able to purchase a 128GB iPhone 7 during this last sale. My question is: I've found that the battery life isn't quite what I'd like; can I exchange my 7 for a 7 Plus and continue to pay the promotional price? I am paying a little extra for the more storage, and I understand the 7 Plus is on top of that. Can I exchange my promotional 7 for a promotional 7 Plus? Also, can I exchange in-store if I bought online? Thanks!
