This was my first attempt at using uShip. I listed my item and my first problem was that when I checked the next morning, I was "booked" with 3 shippers and 2 had already called my office! With only one bike to ship, 2 were disappointed, and pissed, as apparently you charge them for every "booking". I may have made a mistake in my listing but your software shouldn't permit multiple bookings for a single item.
I also had trouble leaving feedback.
uShip is a great idea but doesn't appear to be quite "ready for prime time".
