I have been at bonanzle for two months and sales are a little slow compared to ebay. Since Its free to have your booth does not affect me much.
Unlike ebay, at Bonanzle one must bring traffic to your booth as mention earlier.
Bonanzle provides tools to bring traffic like Google base feed, craigslist integration, twitter integration and much more.
My main tool for traffic has been craigslist as this point.
my user id at Bonanzle is fairdeals4u
god bless all
