Shipping what? A letter? A two pound package? A twenty pound package? A car?
How fast do you want it ? International Fed Ex / UPS /DHL will get a letter in two days.cost you 50 dollars US. Bigger, heavier, faster = more expensive.
A whole twenty foot container might be as little as five hundred bucks.
Going the other way, one shirt will be $25-$50 to ship by the Post Office with a 2-3 week time frame. Triple that for overnight. Going from Germany to the USA would be about the same.
