Is this possible with Zen Cart?

Hi, Im just wondering if this is possible with Zen Cart?

I am wanting to make a site where customers can put their own items up for sale, you know like on Ebay how you list your own items. It would also be good if I could keep track of what each user has listed, so I can add up how many items each person is listing.

Would that be possible and how would I go about it? i dont mind using an add-on as long as its not a very expensive one, if you know of one that could help please let me know.

Have I been clear enough in my explanation?...
Thanks for your help!

:unsure:

And how are you going to handle payments in this
scenario?

The short answer is that it can be done, but it is a LOT of custom coding which you will have to do yourself, or hire out.
Kuroi built such a system some time back (officetraders.com, I believe) - look for his post about it.

There is supposed to be an "auction" mod, which might help you.
