When using Upside, prepaid receipts are not accepted as proof of purchase for your offer. This is because prepaid receipts do not provide us with all of the crucial information we need in order to process the offer and get you your cash back.

To earn cash back, you must use a credit or debit card to make your purchase and have proof of this by either your purchase being verified via transaction data, or when you submit a picture of your receipt in the app.
