Advertising on forums that are specific to what you're selling. I sell firearms, firearm accessories, and ammunition, so I spend a great deal of time on forums. One of the best is SomethingAwful. They have a sub-forum dedicated to firearms, and a very close knit community. An ad on SA costs $30 for a month (which is insanely cheap) and I started a thread advertising my company. We've done incredibly well that way, have already sponsored a competitive shooting team and met a bunch of nice people. What you don't get, of course, is in depth tracking. You can only see how many clicks you get (just wrap the link in your ad around bit.ly or another URL shortener). But it's just as well with me, I know my advertising is hitting it's target audience and it's worked out very well.
