I went to the site and it looked to good to be true! So I googled it for some info.. Here is one of the things I found about it..
your charged $0.60 each bid, seems like a way for the company to break even, but since each bid is either 1 or 2 cents increments. 1 dollar of bidding is either $60.00 @ 1cent or $30.00 @ 2 cents. so when you see the playstation 3 on there for $66.78 @ a 2 cent bid, that means the company has made $2,003.40 off of a $300 dollar playstation on top of the ending bid u also have to pay.
So legal yes, but also waste of your time, but for Quibids its a great way to sell a ps3 for 6.67 times its actual value.
