No idea what you mean by CM or LM.
But if you look at the bill from fedex there will be a tariff code listed.
It'll be something like 64xx.xx.xx.xx where the x's are digits.
Look it up in chapter 64. http://www.usitc.gov/tata/hts/bychapter/index.htm
If the description is wildly different, you can try and fight fedex for a refund.
I usually figure on about 8.5% so $84 sounds high for Meermin. But ask yourself how much your time is worth to get it corrected.
