Would be great if someone could develop a mobile optimized Amazon payments plugin for wordpress. If the user does not have to leave your site to check in to amazon, that would be even better.
Amazon Payments is a way for users to make purchases using their Amazon account. It’s just another payment gateway like the many others that are out there.
You can create and add a button manually, but the problem is – the process isn’t mobile optimized which makes for a bad user experience.
