I can't be sure but I don't think they count the pallet as adding anything -- I may be wrong, but as far as I could tell, they just took my boxes as the final volume. I didn't get any notices about being over the limit, or have to pay extra...I think that when I was stacking the packed boxes, I did my own rough measurement of the cubic feet, and it must have been not too far from accurate, as I never heard anything from UPak at a later date, nor did their quoted price change (which was a relief).
As for books, funny, but those were the greater part of what I was shipping; everything was in the condition I sent it in -- the only thing that suffered any was an oil painting that I didn't pack properly and the paint slightly melted then reset. But this was a shipment leaving Houston TX in the height of the July 100 degree heat, ocean freighting through the Gulf of Mexico, so I@m not surprised something got heat stroke, lol. Other than that, all my stuff fared really well, including electronic items and musical instruments.
