If you enter 10 x $100 VISA gift cards to Amazon Payments, do you have to send $100 ten separate times to another person? Or can you send $1,000 and the system will continually ask you for more payment methods until you reach $1,000? By the way, I was able to enter the 10 x $100 gift cards to my regular Amazon account and they are all available in my Amazon Payment account to fund payments.
