I did the ad campaign on FB. It worked great, got us about 10 new leads a day for a week. With a daily budget set at $8. It bumped us over the 100 likes mark, but I can't say that that has generated any sales for us. If anything, it has made us look a little more legit to others who drop by our page. It's unfortunate that now, if I want to push a post for all of our likes to see I will have to pay for it.
