Was shipping my bike from one state to another --- and I was located in neither of them. Initially concerned about how I was going to coordinate three parties, timeline options and bidding selection.
I lapsed on one bid posting and changed date ranges twice - most bidders were understanding and were able to bid and retract as I needed to change date options.
uShip is simple to use, enables access to a bidder's customer feedback and their profile, although I might have needed direct references if this was a high-value transaction - in my case the bike was not high value and in non-op condition.
I would use this service again
