I've used Doobids a lot recently and I have to say that its very difficult to win auctions. I have won 4 auctions on Doobids but have spent a lot more money than I have saved. The key is to buy big bundles of bids, you see people winning with 1 bid but what you don't see is that person has something like 200 bids behind them. If you want to be within a shot of winning you need to buy at least 100 bids and DO NOT bid on weekends as most of the good auctions only start at 11.00pm and all the bidders with 500+ bids will bid on these auctions. Trust me don't make the same mistake I did. However one of the better things with Doobids is that your guaranteed to win at least 1 auction as they have rookie auctions on everyday and theirs normally only one person trying to win them. They can range from a DVD to an PS3 game.
