Looking for vb sale system (to allow users to sell items on vb-board)

[Steelbelted]

Hello! :)

Im fairly new to vBulletin, but has to say that im really impressed by the flexibility of this product, and all
the fancy modules readily available for download!

Im running vbulletin+vba+vbseo on a new norwegian discussion board for cars,boats,mc`s etc.
What im looking for is a vb-plugin that allows my users to buy/sell items (free) on my site.

Does anyone know of any plugins that can allow me to do this ?

Thanks!
