Where is it best to promote a Bido auctions

[justwondering]

I currently have 13 voted to auction listings on Bido.com , where would be best to promote these , most of the other main sites , either require paid for membership to promote / offer a name for sale or its 1 listing a day .

Has anyone had any experince with bido auctions ? either selling or buying , is it a good / average or bad service.
