I have a small web site with only a few products. I am looking for a way to add buy now buttons to the existing site. I would also like a shopping cart link with running total at the top of every web page.
I do not want a catalog. Basically I want just a professional checkout screen with options to use different shipping options and payment gateways, not a cheesy Paypal link.
Is it possible with Zen Cart? Are there other products anyone can recommend?
