Returns?

In my haste I accidentally purchased 2 airport extreme cards via the apple online store. This was late at night so I couldnt call and cancel immediately. Well I called the next day and while the products hadnt shipped yet, its already gone through apples shipping process and therefore cannot be cancelled. The two products will be shipped separately, different dates. So my question is can I just refuse a package when Fedex/UPS brings it in? (To avoid fees on shipping it back to apple.) I know I can just write "Return to sender!" and send it back via USPS, if it was shipped that way. But apple uses Fedex/UPS. Any ideas?

 

Thanks for that! I wasnt sure if I could do the same with fedex/ups. Its a standard airport extreme card off their web site, so I guess it shouldnt be a problem then. Thanks again!
