Ecommerce where user can post and sell?

Is there any free ecommerce full script where user can post and sell their stuffs.

Marketplace kind of thing.

Would be really great ful for one.

Thank you very much.

I didnt find good one so i wrote one myself…
It is doing most of the things
Does not have all the features like that of opencart and magento but do have lots of features and does the job

Try Zencart
Which is available in softaculus if active in cpanel…
otherwise search online

yes, opencart can offer.

Try osclass
