Can You Use 2 Prepaid Credit Cards On Paypal For One Item?

You’d have to use them both to move money to your paypal account before going through the checkout procedure (ie use them to put a positive credit into your paypal account).
-edit-
Log onto PayPal.
Get to the Account Overview page.
You’ll see a two layer menu bar. The top layer of that menu bar reads>
“My Account – Send Money – Request Money – etc”,
the SECOND layer of that menu bar reads>
“Overview – Add Funds – Withdraw – history”.
You want the ADD FUNDS tab on the second layer of that menu. It should be straight forward from that point on, but you may need to set up the cards in advance if it will let you.
*we have two accounts here and mine is set up to allow this, but the other will only allow funds to be transfered from a bank account for some reason.
