I had the same issue. My 2 cents:
1. WAIT. FlipFinder finds ads posted NOW or IN THE FUTURE. They don't look in the past (the good deals are already sold so it is future based only).
2. Make sure you are not too specific in your searches.
3. Make sure your cars are spelled right ;)
4. Try "Entire USA". You can ship cars to you anyway and the prices tend to be less and results will skyrocket.
