are we so advanced that we got it down to the exact minute when milk will go bad? i'm really curious about that. i checked another carton of milk and it said 23:30. i'd like to know if that is really the expiration time. cos that is pretty sci-fi. anyone can enlighten me? will the milk turn sour at 3.08pm on the 6th of feb? i'm tempted to leave bit of milk till after the expiry time to taste it. by the way, this milk is expensive. over 3 bucks. i've switched to daisy hi-lo. why don't they sell milk in bigger cartons/bottles like in perth? these tall tower cartons don't hold a lot of milk. which is prob why daisy hi-lo has the buy two packs for a cheaper price deal.
