..... right on! ............. though it should be noted that a product may not last until it's Best Before Date, because of how we the consumer have handled and cared for it.

A prime example is milk ... how long was it out of refrigeration from when you purchased it in the store until you got home? Was it -22°C for that drive? or +38°C? Is it removed from the frig, glass poured and returned to the frig? Or does it sit on the table for an hour during a meal? Or longer, while family members come and go from the table? Is the container/bag closed/sealed between uses? Or opportunities for cross contamination with other foods? etc.

This is just an example using milk, but you can take the same concept and cross it over to other food items.
