WARNING. I sent a package to canada, the importers called me up to ask me how much it was worth and I told them it was insured for $150 and then they called me back up and wanted to see how much they paid and i faxed them a invoice of $1200. They took the whole package and said I have to pay $900 to get it back since i wrote on the package it was insured for $150 and not $1200. I am insured by a private insurance company on all the packages I sent out for up to $25,000 so I did not want to insure this package again with usps. I am stuck.
