Deal Dash- May be the biggest penny auction site around. They have tons of auctions and have deals on bids as low as 12 cents. I have won 20 different times on this site and received 18 of the items. Still waiting on two of them. Customer service is terrible they do not respond to emails. However they are a legit site and send the items with free shipping. It has become more difficult than ever to win auctions. So many people on deal dash. Many of the easy to win items are even becoming difficult. If you think you are going to win an auction by placing a bid buddy and going to bed... think again. There are snipers waiting and snipers waiting on snipers. I am not saying you won't win but you probably won't with the bid buddy unless you purchased a lot of bids and bid on it when it's higher than average selling price. Also... they say they will give you 200 free bids for posting your picture with your winning item of over $200 on the facebook page. Well I did that and they even clicked that they liked it but no free bids and no response to my email asking about it either. Some good ... Some bad.

Quibids is a popular penny auction site. They don't have nearly as many auctions as dealdash does but they are legit and send your item fast. I don't have as much experience with these guys but I have won a couple gift cards from them and received the items fast!! What I like best about these guys are the rewards. If you refer a friend who purchases a bid pack they will give you 25 free bids! Gotta love that. If you wanted to try just one site I would recommend this one.
