PayPal has stated that Vanilla Gift Cards don’t work with there payment processing system due to AML concerns. With most gift cards you can register your name and address on the card issuer’s website so it matches when checked by the online retailer. Don’t use the Bank street address found on the Cardholder’s Agreement.
