"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I am not entirely sure I fully understand what you are looking for.  I think you want a shopping cart where you can post products by categories for sale with the parameters you are looking for such as comments and email.  Just about every shopping cart can do this.
