Are there any viable alternatives to Paypal for a small site?
While I've never used the service, there's also Amazon Flexible Payments Services (AFPS): (emphasis below is mine) Amazon Flexible Payments ServiceTM   (Amazon FPS) is the first payments   service designed from the ground up   for developers. It is built on top of   Amazon’s reliable and scalable   payments infrastructure and provides   developers with a convenient way to   charge Amazon’s tens of millions of   customers (with their permission, of   course!). Amazon customers can pay   using the same login credentials,   shipping address and payment   information they already have on file   with Amazon. [...] Considering Amazon.com is an e-commerce heavyweight, it might be worth a look.
