It makes no difference who you ship the package with, it will be examined by customs and you will pay duties on that import. Packages coming into the USA do not just slip in due to large quantities, they go through customs and each package has paperwork that is filled out and classified and then a duty fee is determined and charged. If you have not placed an order yet, your best bet is to buy a laser that has an FDA accession number (FDA approved) or buy from a relatively unknown company, I would be very careful ordering from wickedlaser; after the latest news stories they are becoming very infamous and if customs has not been told by the FBI or FDA to closely examine shipments from them for units that are either >5mw or not FDA approved, they soon will.
