So I just recently did a trade in with Amazon for some of my textbooks and acquired $181.90. Now what I want to know is; How can I e-mail a Gift card by deducting balance from this? Is it even possible? I went through the e-mail a gift card procedure and when I got to the payment screen, it asked for a credit card. I was hoping to pay it with the balance on my account. Reason I need to transfer it is because I got the Free Amazon Prime for having a .edu address, but the balance is actually on my personal e-mail. So I need to transfer it over to take advantage of the Prime. Any help is appreciateD!
