Priceshuffle.com deceptive charges Internet

Also ripped off with $ 149.75 charge on credit card after believing I would get 100 bids for free from an ad on a sports website for penny stocks. Ad showed how to get 100 bids for free and i followed through. Not reading the fine print, after using site for a few bids, received e-mail for 149.75 charge for 300 bids plus the 100. Wrote them back suggesting i wanted the 50 bids to start, but they refused me and pointed to the hidden charges. I have since offered to minimize my losses by paying .50 per bid used which was now at 132 bids for $66.00. Am certain they will deny the offer even though I was willing to return the free bids. By the way, their product line is very small and doesn't seem to change......
