I have milk in my refrigerator right now that has a 1/5 date stamp on it. Just had a bowl of cereal and tea for breakfast this morning, and it all tasted fine.
You can trust me on this one -- I am an uber-paranoid freak about expiration dates!!

I think it's a matter of personal taste. I find milk to be repulsive by the time it reaches the "sell by" date.
I freeze my meat so no worries on that, and just about everything else I ignore the exp date on. If it still tastes fine and doesn't have mold I'll eat it!
