A client of mine paid me for some work with a few visa gift cards. He also gave me a number I called with Skype (toll free) and checked the balance of the cards, and it's legit. But now I don't know how to get that money to my Paypal account. The gift cards are just a 16-digit number + expiration date + 3-digit number. Anyone has any ideas how I can get that money from the cards to my Paypal?
