Ask HN: Amazon API Question

My programmers and I are trying to figure out if this is possible. I would much appreciate any input.

Is it possible to create a website where people can create accounts with a credit card and shipping info and purchase Amazon products from this separate site? As in, our site would store CC and shipping info and transfer them to Amazon when a sale is made so that they fulfill the order (and still receive a cut or commission).

Came across Amazon MWS (https://developer.amazonservices.com/gp/mws/index.html/183-8675474-3819327) and thought it may potentially help make this possible.

What do you guys think? Is it technically possible?
