Tear off the bottom part of your receipt. That is the only part you need to mail in for the rebate.
When I used mine for the rebate I tore off the bottom portion of the receipt, sent that in for the rebate and still had the original in hand. Give em a call or talk to someone at the service desk, they will be able to help you.
Make a photo copy, but I'd call both entities to make sure which to send copy to
