Oh Dear! Didn't even realize there were expiration dates. Just went through them all. Here's what we've got: 6/1/12 - 3 12/31/12 - 7 That leaves 191 with expiration dates from 2013 - 2016. No expiration dates on the milk lids.
Just some info on the Kemps Nickels for school milk lids....They've ended redeeming the lids since November 1st, 2012. Had just checked their website....
