Then it's another Fail.

If you use the underlying FPS APIs, I believe you can set up recurring payments with no logins (I'm only going on docs, I haven't had direct coding experience with FPS yet).

Quoting from http://aws.amazon.com/fps/faqs/#What_can_I_do_with_Amazon_FP...

"Use tokens to execute one-time or multiple payments or recurring payments on behalf of customers."

And from http://aws.amazon.com/fps/faqs/#What_payment_methods_does_Am...

"Amazon FPS supports the following payment methods:

- Bank Account debits

- Amazon Payments balance

- Credit Cards (Visa, MasterCard, American Express, Discover, Diners Club, and JCB).

It looks like the "Amazon Payments" option is what this Simple Pay subscription is employing, right?

I'm pretty certain that whomever is the source of the funds is still required to have an amazon account. I'd love to be wrong about this.

You're right. I just took the time to look deeper into the FPS documentation.

So I'm getting the impression authorize.net is what most people here use for no-account recurring payments?
