Looking for a store plugin… the ecommerce

I’d like to create a portal for my client that will allow them to post sale items on a “store” page, but there is no purchase function needed. So it’s an ecommerce-lite plugin. Any ideas for me? So far I kind of ruled out AWPCP Classifieds as that doesn’t allow a unique user role that excludes Subscribers, Contributors, Authors and Editors. I’d like the post function to remain on the front end, not through the dashboard.
