Too Good to be True?

I just read an offer that promises, for $89 to send 30,000 people to my website.

30 THOUSAND. Wow.

And it says they will be targeted to people who would actually be interested in Stuff for Sprouts (although that part isn't so specific). I need to know more.

30 THOUSAND people coming to visit Stuff for Sprouts. At least SOME of those people would buy things. Right? For $89 it doesn't even have to be that many people buying to be an interesting experiment.

Or is this some total sucker deal? I am losing all perspective.
