This is my first experience developing a site for myself, and my first experience with eCommerce. I thought the eCommerce thing would be complex and difficult, but it took me less than 1 hour installing Documents Seller, learning its basic use, creating some categories and products, linking to paypal, and successfully sell my first product.
Bottom Line: the technical part of eCommerce was the easiest part of my project thanks to Documents Seller.
The extension worked exacly as it should, there are a lot of clearly organized configuration options, and it is very easy to use.
I also got very good support from the developer. I asked him for some customizations, and he developed them ovenight! Fast and efficient support.
I totally recommend this extension.
