How do I sell something on Amazon?

So, I am selling a couple games that I bought and didn't like, and I'm selling them dirt cheap cause their used, and I personally don't think they were worth what I payed, I really want to sell them on Amazon, I have an account there, but I'm 16, I have no credit card, therefore I can't do Paypal, So... My mom does though, I'd ask my Dad to do it on Ebay for me, but I've probably asked him 100 times if I gave him the money, would be buy me something on there, and he ignored me, also, I was on another online store, and they had a policy where you you had to buy a certain amount of items before you could sell, so, How would I go about selling on Amazon, should I ask my mother, or is there another option to get the cash? Thanks guys!
