They usually are all over the world. But some interesting economics starts becoming apparent when packaged food products approach the last 1/3rd or 1/4th of their shelf life. For e.g. - near-expiry food products being exported from developed countries to developing ones (where they still command a premium over local products). I've found entire shelves of imported food products just months away from expiry (out of a total shelf life of, say, 2 years) - re-badging of expiry dates/lots by unscrupulous importers - 2 for 1 offers in supermarkets to liquidate near-expiry stock
