If you use iOS (not sure if we have it on Android just yet) then I'd recommend looking for something called "auto-buy" when you search for a flight. It's basically a limit order for flights and it'll allow you to set a price that you would be comfortable buying at. If the fare dips to that price then it'll book for you. We've seen some insane deals get booked through this product. Just looking at some of them from yesterday there was a round-trip flight from NFO (Norfolk, Virgina) to MCO (Orlando, Florida) that we originally price quoted at $284 for the user and it was booked at $166.
