Each store has it's own weird quirky sometimes outlandish policies and even though they are written somewhere they seem as though they shift and change from person to person so all you can do is be honest have as much of the original packaging as you can find and seriously , unless you have a receipt or proof of purchase I wouldn't waste the trip to the store
Depends on how long you've had them. I believe there is a certain time given to return items bought from Apple.
