Too good to be true?

Who knows if this is true considering I got it in a chain mail. But In & Out is celebrating it's 60th anniversary.

In-n-Out's 60^th Year Anniversary is Wednesday, October 22^nd. All hamburgers will be sold for 25 cents, Cheeseburgers 30 cents, Fries 15 cents, and drinks are 10 cents!!! So mark your calendars!

I really hope this is true I will be a fat cow that day, forget the diet.
