What's the best way to SE logitech reciept wise?

[ReallyGreenBean]

They recently started calling and checking Walmart to see if the receipt is legit, so should I change my story and say I don't have the receipt? What receipts can they not check? I'm getting some of the products I SE to my house so I can just use some pairs for purposes of the SE, like when they ask u to stick the fucking thing in the water. That will make shit so much easier, but in the meantime this receipt thing is killing me
