I just heard about a new service by Amazon called Mobile Payments. It is basically a payment gateway that allows merchants to use Amazons Payment Module to process payments in their own store. Payments with 1-Click from the Mobile are also possible. I think this would be a nice solution for mp3 sales. They have an API that allows feedback to third party systems if the payment was successful etc. Do you have any plans to integrate MPS into E-Junkie shopping cart? I think many people would profit from this because a lot of customers already have an Amazon account, like we profit from Ebay customers having a Paypal account.
