Hello,
please help me with some information regarding platforms (like CsCart, Open, Xcart…) for an online exchange site (for personal things).
For example:[list]
[]users post in their account what are their things for exchange (mobile, shoes, …)
[]other user can see this and make proposal
[*]after one or more proposal are acceped, they should close the deal (sendind one to each other their stuff).
[/list]
Please help, because I’m stuck… 
All the best,
Cosmin
Multivendor edition. Users (sellers) would sign up as vendors. Customers would purchase normally or you could have some specific zero price actions (like a test field for their proposal).
