Op wants to be able to send in the device he bought at a retail location to Apple.com. He has to return it to the retail location, where he purchased the device. You can't return a store bought item by mail. Never heard of this being done.
Except for pretty much every other manufacturer of course.
If you buy something from, say, Panasonic in a shop and the shop then goes bust the next day, you are entitled to send it back to Panasonic if it breaks down a few days later.
