I had an Xmas tree to have transported from Fl to Ga. I posted a shipment and received a bid and accepted it. Uship charged me a $24.99 fee. They never disclosed that the transporter also had to pay a similar fee. When a problem occurred they began a negotiation CHAIN between the shipper and transporter. While they were very happy to facilitate these discussions they never participated in reducing their fees. Their fees actually amount to 30-40% of the fees paid by the shipper, but they provide little value beyond the IT web site infrastructure.
I would never use their services for future moves, besides their outrageous fees, the vetting of the transporters falls woefully short of reasonable standards.
