Can a company be sued for over charging shipping and handling cost?

I purchase some parts from RockAuto and they shipped them in 5 shipments. 2 of them were with a freight liner. I just got one of the parts today from the freight liner and turns out the part could have been shipped through a smaller carrier i.e UPS/FexEx. The dimensions of the box were 47 1/2 x 36 1/2 x 10 3/4. I calculated the girth as I know the smaller carrier will not accept anything about a certain girth and it came up to 83.75. According to FexEx "With FedEx Express® U.S. services, you can ship packages up to 150 lbs.; up to 119" in length and 165" in length and girth. • With FedEx Express international services, you can ship packages up to 150 lbs.; up to 108" in length and 130" in length and girth" - this is from their General Package Guidelines. I wonder how many other consumers have been taken advantage of this.
