Question on shipping to the West coast

Hi,

Wondering if someone can give me some insight on what I suspect might be overcharging by a truck broker.

We ship freight from the east coast to the west coast, this particular broker came to us and said, we have this way to get freight over to the west coast faster than straight intermodal but it costs a little more. They said what they will do is pick up the freight on the east coast with an over the road driver.... who will drive the load to Chicago and drop off the Intermodal container at the rail yard in Chicago. From there the container will be put on the train and deliver to the west coast. They are charging us $900 more to ship this way compared to straight intermodal. By doing this we would supposedly save 3 days on the transit time... (7 days compared to 10 days). Everytime they do this for us they use a container with a JB Hunt 4 letter designation. So I went on the JB Hunt public tracking site and looked up the shipments. It seems they are all being put on the rail on the East Coast and not shipping to Chicago. They are all still delivering in 7 days, but they are not going over the road to Chicago as they first proposed. If they can deliver via intermodal in 7 days, shouldn't they tell us that and charge the intermodal rate?

Thoughts or any insights would be appreciated before we bring this information to the attention of the brokers salesperson?

Thanks!
