Absorbator

Thanks for the answer. I played a little with the model/view scripts (or controllers) and I found that it is not so hard to customize opencart.

I'm looking for a eCommerce software that can be customized easily. So far I've tried OpenCart but I find it unnecessarily complex and very clumsy in terms of customization. I can't even get rid of the demo products !!! I need an application or a library that simply does its server-side job and allows me to easily customize it with scripts (I have a long experience with PHP, so that's not a problem). Any recommendations are appreciated
