1099-K & Rebate Key

Hello!  I do not sell anything.  I use Paypal to send and receive payments from friends and receive cashback/rebates back from Rebate Key which is over $600.  I purchase items at full price through Rebatekey & Amazon, Ebay, Etsy, etc... and Rebatekey gives me money back via Paypal for the discounted price the seller is offering through Rebatekey's website.  I'm worried I'll get a 1099-K and don't feel I should have to claim any of it since it's nothing I'm selling.  If I do receive a 1099-K, is there a way for me not to claim that "Income" since it's not income?  Thanks!
