auctions online

i have seen so many people go online and bid for items that gives u items that u can bid on but the only bad thing about it is that people dont know how much money u can lose from doing this kind if auctions (game) the on like auction is not free to bid on an item u need to buy bids frist that can charge around 70$ for about 100 bids that mean u can only click 100 times and though 70 $ alway and not get any items i think this is a bay way to invest money. also the site makes so much money if people for exp. the other day they sold a new car for only 1000 $ thats about 1000 bids that mean the site makes over $100.000 off of bids. somd if the names of the site at beebids.com, quibids onlineibids and many more
