Is not a scam, is no different from all the other penny auction sites. I have won auctions on Doobids as much as I have lost too. All in all I do very well but I do believe you need your own tactics. Just pumping straight cash is sure to make you angry win or lose. I've never bid as many bids as that and I certainly never will. I have won 17 auctions on Doobids but I have probably lost just as many if not more maybe. One thing that is different from other penny auctions is that it is a newer business so there are much less customers, but saying that it can get really busy on the weekends. I think more people are converting to doobids over some of the other smaller and certainly more suspect penny sites. Still better chances on doobids than madbids and swoopo though, much better chance!
