Also true. Apparently, if a product exceeds the expiration date time, it’s supposed to be thrown away.
When a product’s expiration date is coming soon (usually the next day), the product will often sell for a discounted price.
With the exception of baby formula, the expiration date is only a BEST BY date. That means the food will be best until the expiration date, but still consumable after.
However, for baby formula, the expiration date is a strict safety date. When baby formula exceeds the expiration date, it’s no longer safe for consumption.
