shipping only to the US

If you're using the Post Office (and you should when sending parts to Canada or Europe) and do it on-line, you just need to fill in the blanks on the address and customs form and it will print automatically. The only other thing you need is the clear plastic envelope the PO requires for the customs/address labels. You can even have your carrier pick them up and leave them in your mail box for you. When you're ready to ship do a carrier pick-up and the carrier will come right to your house and pick up the package. Really guys, it's that easy! I do this all the time and it's no big deal!
