So I KNOW that I have more than enough money for the $10 purchase I am trying to make, but I don't actually have $10 on one card, its just spread out on different ones. Anyway that I can use all of the cards to make the payment?
No, sorry. That is only possible with eBay gift cards. Regular visa/MasterCard type gift cards has to have the amount to cover the purchase in one card.
The type of transaction you are referring to is called a split tender. As far as using an online cart for split tender would not be possible. The transaction would only be possible if manually entered on the merchants end. If the store has a real merchant account they can possibly run it. If they are only using PP for payments you are probably out of luck. Have you tried contacting the seller to see if they can accept split tender?
