itsyBiD is a Penny Auction (pay-to-bid) site. We operated successfully for 9 months, and have turned the site off for change in direction: We will become the ONLY Penny Auction site for non-profits/charities to auction items and raise money. With the Penny Auction model, Charities can potentially turn a $100 item into full retail or MUCH more.
There is a large market of penny auction bidders, and a huge number of causes seeking fund-raising. The potential market size is enormous.
