Hello, I bought a 9.7" iPad Pro and (stupidly) paid with cash. I then decided that I wanted the larger version, so, when I returned it, the manager at the Apple Store said that Apple would have to mail me a check. I know that Apple policy says that "Apple will mail you a refund check within 10 days". I wondered how many of you had experience with receiving refunds from Apple this way? Do the refund checks come within 10 days? Do they take longer? Thanks for reading!
