I once spent six hours calling around for quotes on a 400 mile move and ended up saving exactly $12, which works out to two bucks an hour for my time. My wife still brings that up at dinner parties. So $340 on Denver to Seattle is a real win, good for you. The smaller brokers sometimes just have less overhead and can pass it on. Big names charge for the brand I guess. I learned my lesson and now I just pick one and move on with my life.
