Last night on the way home from work, stopped by the LFS to pick up some salt (Tropic Marin). Didn't think much of it, but when I got home I noticed it had two dates on it. One date was 10-06. Guess that's when it was made. The other date was 3/30/09. Was that an expiration date? Hope I didn't drop a buttload of cash on crappy salt. ???
