"Greeting from Amazon Payments,
Our records indicate that you are using Amazon Flexible Payments Service (FPS) or Amazon Simple Pay (ASP) to process payments. We want to let you know that we are retiring the FPS and ASP services as we transition to our new solution: Login and Pay with Amazon. These services will not be available after June 1, 2015. We recommend that you migrate to Login and Pay with Amazon, to continue to access the growing base of millions of Amazon customers."
