First time we have ever bought anything like a boat online, was more than a little stressful getting all the dots to line up. We had expected shipping to be yet another set of challenges, but were pleasantly surprised by the process and the service provider we chose. I would add that we did not pick the least expensive bid, rather the bid that was the most definite in terms of pickup and delivery dates, that had the best feedback history, and still was competitive.
We paid a little more, but were completely satisfied and did not have to spend days and days without knowing definite dates and times for pickup or delivery.
A good tip would be to offer - if you can - to wait until shipper has booked a backhaul - that reduces price - but once he does, then insist on definite pickup and delivery dates. As soon as we set these perimiters, the bids really started to drop.
We absolutely would use U-Ship and specialistmovers again. Delivered as promised, at price agreed, and on time.
