I guess it's out of the question for performace to post the expiration date of the clearanced items so that the consumers know what they're getting?

As far as consuming any of the mentioned products after the printed expiration date, I'd assume from other's experience that this is probably all right to do. Nobody here has complained of any ill effects, and I've not seen any other posts on the subject. I do have a follow-up proposition for group consideration: Perhaps the expiration date is not the date the comanies expect the food to go bad, but some estimated date that they think they might lose some of their effectiveness? Or maybe more simply, they expect that the product won't be as fresh?
