As long as it looks/smells good and has no obvious "bad stuff" growing on it, I'll eat it, even if it's past the "best by" or expiration date.

EDIT: And, yeah, same as Karen with eggs, milk, etc... I've had some gallons last a week after the "Expiration", and I've had some gallons (like the one I threw out yesterday) that went bad ON the expiration date ugh.
