Amazon Payments
 

Is anyone using this in any way, shape or form?

Looks like Amazon is going to try and take some of Paypal's marketshare.

I have been using checkout by amazon for over a year on a mainstream site. I don't have any experience with the send/receive money feature.

If their payment support is anything like their seller support, I will not be touching it with a 10 foot pole.
