I like your attitude to the free website, why not indeed. I suggest you actually expand that to free listing auction type sites like a bonanza.com. Sure, not a massive traffic, but the point is it's free to list and it is at least getting some exposure, so why not?
Just drop some details of what type of products you're looking for under the dropship or supplier wanted categories and Rachel will be happy to assist in helping with that.
