I'm going to be picking up a 5C in a few days at Walmart since it's a great deal. Originally I was planning to buy at an Apple Store, since I know I'd be able to bring it there for help. If I buy it elsewhere can I still bring it in? I've never dealt with Apple customer service before so I have no clue. I was planning to put the savings towards AppleCare as well, so if I purchase that can I take to an Apple Store for replacements?
