HappyBidDay is one of a new slew of penny auction websites on which one can win brand new items for dirt cheap prices. Plasma televisions can be won for just a few dollars. $50 Gift cards can be won for pennies. Stereo systems can be won for $25. In theory anyway. The competition is often fierce, but winners almost always walk away with items at dirt cheap prices. The catch is that you pay for each bid. All costs considered, the take home prices still stay ridiculously low.
