If I bought a box of cereal in June 2013 and the box says use by 3/2013 is this still good to eat?
You could take it back to the store, it was already out of date when you bought it.
You could still eat it, although it's likely going to be stale like Walt said.
what type of cereal was it *-*
No just don't eat it just incase
U bought it expired. March was the expiration date and u bought 3 month after ( June ).
