Single page checkout script or cart

[sherry_d]

I am looking for a script or way that can take a users info and process their credit card on one page, really simple and that can be put into an existing site design easily. And I wanted to use PayPal Payments Pro but can consider other merchant accounts. Has anyone seen anything like this?? Any info would be great!! I want something like this https://www3.secureinternetstores.co...ex&r=s0pai1mds or this
