Recyclebank has teamed up with Amtrak to offer you 10 points.  Click HERE to sign in or up with Recyclebank.  Then click on the Earn tab at the top of the page.  A list of opportunities will come up and the Amtrak offer should be on the first row.  It will redirect you to their Facebook page but I was able to get the 10 points without having to "like" them.
