I'm pretty sure there is not a shopping cart involved. You just click the item and it aggregates your shipments as necessary and automatically selects destination and payment as configured by the user. It's a business process which I thought were not patentable but it was reaffirmed in 2007. It's set to expire in 2017 so in a few years whatever advantage this patent gave Amazon will dissolve. Personally, I'm scared of all the half-assed implementations that will no doubt mushroom all over the web at that time. http://en.wikipedia.org/wiki/1-Click http://en.wikipedia.org/wiki/1-Click
