Multiple Ubercart? Trying to do a multi-seller site. Hello Drupal community. I'm trying to create a seller's site. This is what it needs to do:

A seller will have his own system in which customers can buy him directly.

The products that the seller will sell will be in common from all the sellers. But each seller will need to be able to set his own price.

I found ubercart (I found it amazing!!!), and it does much more than I'm asking for. I would like to know what should I do? Write a module from scratch? Extend Ubercart? Is there a multiple ubercart possibility?

Thanks for the replies!
Have a look at Marketplace.

The modern alternative to ubercart is commerce and there is a marketplace module too, though it's still in beta.
