what is it? whatever it is (shipping class) will affect pricing.
Class 50 is misc metals (if I remember right...) and ships fairly cheap. I thin Class 85 is used auto parts and has a surcharge on it due to potential hazards...
Define what it is, exact size, if you will drop it off at terminal, or picked up at residence, picked up at business, etc. and it will affect price...
I've always had good luck with AAA Cooper. Most competetive by far, so much so that I quite getting pricing and just using them 100%. Prob shipped out 200 pallets in a years time...
