Amtrak is offering 250 Guest Rewards points for picking up a ticket at a QuikTrak machine by March 31.

Log into your Amtrak Guest Rewards account and then register for the promo using code 11906.

Alas the bonus is limited to one per member.

Update: The promo didn’t say anything about being targeted, but a reader emails a response that it’s in invalid offer so it might just be targeted. You’d think that Guest Rewards would say that if it is, but the folks running this program are among the worst in the industry so nothing surprises me at all.
