it's a cute way of biding thou. this is seriously the first time i heard of "the lowest bid wins"..what a great event they created in the youth club. u can further view on . then u click it on "learn how it works."
the great thing about this bid is u might win cool prizes like ipod nano 8GB. all u need to do is sign up and the cool prizes might be yours!! wish u gudluck and all the best!! =D
