I had to move out of state for work, and my employer did not provide enough money to pay for a national mover. I was nervous about using Uship.com, but now I'm singing its praises. I put in a bid with a maximum amount I would pay and got a shipper within a few minutes. I was extremely happy with the shipper, Six 75. He and his crew were professional, friendly, trustworthy and easy to work with.
I do think it can be a bit difficult to properly estimate the amount of stuff you have for a household move. It's important to do that part of the bid slowly and thoughtfully. Mid-way through our move, the shipper politely told me that he believed I had underestimated the amount of stuff. I agreed, so I agreed to pay him an additional $500.
