I have experienced problems with US online shops. While I make weekly bargains with European and Chinese sellers and pay using Paypal without problem, from the beginning of this year all my tries with US sellers have failed because they get incorrect delivery address from Paypal. Knowing that it is correct and all sellers over the world get it right I have to make an outcome that US sellers use a third party (CIA, FBI, lol-organisations) as a middleman. It doesn't help either to give them right delivery address by email, they twist it again.
