Then let me rephrase in plainer English:DFW said:Yes we know this. That is why the original question. Which isn't answered by your post. Good try though.
THEY DON'T.
If your freight ain't moving NOW, it's costing you money. Period. Anyone who has dealt with contracting goods knows that contracting includes where to be delivered and a "delivered by" date. Unless you know a J6 transport is due in you're not going to wait.
You as the shipper are not going to sit around and pray that Fed Ex will be sending a truck 'round your way some time soon when you have offices for UPS, DHL, or even USPS in your town who can carry it and carry it now. Unless you are looking to contract regular services the 'bidding' is reduced to one wave to each office asking "I have X tons of <something> dimensions of <ht x lgth x width> going to (name destination). How much to pick up and deliver by (name a date).
Trust me I did my share of contracting computer buys, as well as mobile/hand-held radios and cell phones while in the Air Force. NOTHING sits on a dock 'just in case' a better cargo carrier will come by.
