Small Biz Shopping cart

I have a small business and only sell one product. Zen cart and Volusion templates are built for many products so my design looks strange.

Any recommendations on a cart/system that integrates with Authorize.net and with shipping companies?

Thanks!

I use CS-Cart and have customized it many times. It doesn't make much of a difference how many products you are selling. Look Here. This is a CS-Cart site used as a general site selling a few products.

I have used Zencart in the past for a short period of time and they did a great job and very easy to customize.

I have to recommend Prestashop. It's an awesome free open source shopping cart and the community is always growing and contributing to its success. Check it out.

Zeuscart is the best ecommerce software solution to create your online store and it is the most user friendly shopping cart with the easy to the customizable solutions.

I recommend Magento, top of the line ecommerce solution platform offers cutting edge feature, complete flexibility and control over your store. It also takes care of SEO part of the website as well.
