Penny Auction sites are not for everyone. You buy bids like credits. Each time you bid you use a credit. The part that I like is that I can win stuff for great deals if I pay attention and to me its fun!
Penny Purses is a great site because its not too difficult to win and they have lots of different designer brands like Coach and Michael Kors. They also ship for free and have good customer service. I trust them and thats important because some penny auctions are just scams.
