The Best Travel Websites for Saving Money

I love traveling but hate spending money. Going on vacation is bittersweet. No work and getting away (sweet). Spending way too much money and coming home broke (bitter). I just recently started using travel deal websites and am obsessed. They save me money in every aspect of traveling -- whether it's lodging, transportation, food, or flights. The only downside to them is that there are way too many websites trying to help you save money on your vacation. Help rank your favorite websites and give feedback of your experiences and lets create a general consensus to what travel websites really are the best.
