We use UPS for US shipments, which are mostly large items. Every week we get extra charges on the backend. I used to find their invoices difficult to figure out what happened. Now we make an email complaint to our rep for the overcharges (every week!) and get them credited back.
UPS uses some automated measuring system which is often way out of whack. They once decided that I had shipped something 74"x60"x24" in size and gave me a $150 extra charge for it. My rep actually was arguing to me that the system was accurate until I pointed out to him that it was the size of a queen size mattress and wouldn't have fit in the truck. After that there hasn't been any arguing. It is worth noting that I do pay the correct oversize charges when applicable, just not their fantasy oversize charges.
