Also, follow the flights for a few weeks if you have the time. Flights are usually cheapest to buy on a Tuesday. I read an article about it once, and they explained it, but I can't remember now why. I arrange travel at work quite often and I've found the Tuesday thing to usually (Not always) be true. If you will be staying at a hotel, or renting a car do it as a bundle and you'll save money overall. Also, pay attention on the travel sites to whether fees and taxes are included in their price. Some do and some don't, it always looks like the ones that do have a higher price, when one forgets to take that into consideration!
