None are expired. The certificates expire 3/20/14 and 5/1/14. The box tops all range in date. Mostly 6/1/14 and 6/30/14 some are 6/1/15, 12/31/15 12/31/16, 6/1/16. I have a few that are 6/1/13. I have about 150 so it is hard to go through them all. Every box top will be checked before they are mailed just to make sure!
