Has anyone here ever had any luck with penny auction sites? It's obvious that everyone thinks they're scams (no, I'm not hired by any of the sites) but if you do do your research to see what the item sold for previously, your chances are greater, right? Has anyone here actually won? I'm looking at one right now. There's a guarantee that if you spend $100 (I think), you're guaranteed to win something. It really is a smart business strategy if you think about it. But my main question - has anyone here won anything with them?
