if you have packaged popcorn past the expiration date, throw it way because if must be at least 3 years old.
Provided the container is still factory sealed and has been stored properly. See, the "best if used by" date is a recommendation not an expiration date. Even the expiration date is a government mandate. If the product was packaged properly it will last virtually forever.
Generally factory-canned products can last for as long as 2-3 years, though they usually feature a best before/use by date.. If you packaged it yourself, the shelf life will be considerably shorter!

Well, micorwave popcorn is supposed to be used quickly, because they think your probably just going eat it right away. Machine popcorn is supposed to last a while.
ConAgra Foods recommends that you don't consume that product after the best by or sell by date.
If packaged properly, several weeks.
The best way to ruin a Senior prom is to cancel on your date at the last second.
If you can avoid it, try to throw them out and just buy new ones. However, if you really need them, check for any molding and make sure they do not smell foul. Potatoes are pretty hardy vegetables and usually last a while (but I'm not so sure about the pre-packaged kind...)
