I'm glad to work with people that I know from on here or other places on their first time redeeming products if they didn't know about the program. I would need the labels themselves and can forgo the receipts the first time around for you.
The reason that we require the labels themselves and receipts is because we had so many people try to scam us that we almost had to close the program down.
We had people cut out barcodes and send them in for other companies products, people trying to pool products together to do it, and back when we used to give out products for logs and reviews even had people try to redeem product that we had given them for free. I've even had people forward me supposed order confirmations from websites that they edited themselves to make it look like they ordered more than they did - it was ridiculous. So we had to do something or just cancel the program altogether.
