Linkbucks

I found a site for my PSP movie downloading needs and noticed each download goes through linkbucks. Anyone know how much you make per click? I went to the Linkbucks site and couldn't find anything on this.

Intermission - $1.00 / 2000
Pop up- $1.00 / 2500

This is for US traffic, if you have traffic from other places the rate is even lower :/
