I love the idea of the amazon associates aStore--the unbelievably simple way to list products and then get affiliate fees when they sell.

However, I absolutely hate the way the site looks when you put it in my site. It just doesn't have the look and feel I want.

I'd like something that can be made to look more like this:

A very clean, minimalist shop that will work within my site.

Most importantly, I need it unbelievably simple to add products (preferably just by adding links to a form). Can anyone suggest the best easiest way to do this?

Thanks in advance.
