Making Apps Free - What's the best way to promote?

I’ve been considering making my app Sharks Vs. Subs free with ads for a while now, because sales have begun to slow a little and I would love to be able to use it to promote an upcoming app I’m making. I figured I would ask the collective experience of this forum to see what the best way to promote the app’s going to free. I don’t want to spend a ton of money on a campaign, but anything under $100 would be OK. So, what, in your experience, would be the best way for me to promote this app going free?

So i’ve seen a lot of developers do “grass roots” marketing and go on several different forums and announce that their game is going free and sometimes the right people hear and promote it for you. I’ve seen a few people get great results from that. Some forums(especially if they are gaming focused) provide the categories to do this kind of promoting in.
you can use an ad network and target similar demographic to people who already use the game. unfortunately i dont know if $100 will be enough :confused: [import]uid: 174977 topic_id: 30324 reply_id: 122664[/import]
