when you reserve to pick up in store, do you have to have a credit card associated with the apple account? Reason I ask is my primary apple account is for Portuguese store where I live but I'm flying into Bristol on 16th and wanted to collect from the Bath store but don't want hassle of adding/changing credit cards to apple id's.
Nope, no payment details are needed. Last year you were limited to reserving two phones but that is it. Apple aren't worried about people reserving and not turning up as they will just sell it to someone else the following day.
