I recently came across a couple of websites that offer guaranteed signups to your free offers or whatever program you are in. I don't remember the price but I think it was something like $40 for 25 guaranteed signups.

Has anybody ever tried out these services and do they really deliver on what they promise? If it works I would make a killing because I can get $500 for 25 signups.

It sounds a little too good to be true and it usually is.
