I expected this (even got used to it) in the early days of the web but haven't come across it for some time now that it was a bit of a surprise.

So, basically as a non US citizen I can't book tickets on the Amtrak site because anything other than a US ZIP code in your billing address is not acceptable.

I will refrain from a rant about on this subject and just ask, have any other non US members gotten around this problem?

I wrote to Amtrak and they offered to book the ticket for me if I send them the details by email (rather a weak response). Will I still get the discount code reduction though if I do this?
