I use Priceline a lot, as I have mentioned before but another website I often use is Travelocity. This is a good way for me to compare hotels and flights. I don’t always book on this website but I find it a good starting point for pricing things.
I especially like their fare watcher you can sign up for. You can pick up to five different flight destinations and set a price you would like. Then it will notify you if they have something in that price range available.
I’ve noticed that when I search for a hotel a few days later they will send me a coupon for that destination.
