I found a set of ProPanel artist display panels for a great price over the internet, but it appeared shipping them was prohibitive. I found U-Ship and within 2 days had two very reasonable bids. The seller didn't want to deal with packing the panels for shipping, and both bids covered that. Redline Logistics delivered the panels door to door in perfect condition. Without U-Ship I would have given up on this deal.
P.S. To give you some idea of the service I received: my panels rode alongside a $20,000 bronze statue being delivered to a high-end gallery. I'd say they were well taken care of.
