Quoting Jessy Ann:" honestly I don't have the right answer for you but when we cut the corner, it's only a little slip. Also, ... [snip!] ... 4L bags of milk every 3 days, so the freshness really is never a problem. Also I don\t think it's much different than a carton."
Well thats good to know freshness is never a problem, I was only curious because I know some people who take forever to drink a gallon of milk and always complain that it goes bad blah blah blah and are only drinking regular milk until their DD is off WIC which runs out in Nov because she will be 5 and then they are changing to soy/silk (dont know if its the same thing) because if that were them and they had bagged milk they would probably complain about it going to waste and all that crap. My son and I are major milk drinkers as in 2 gallons a week for us. Rarely do we have milk go bad around here. So good thing I dont live in Canada (unless they sell jugs too) because we would be spending ALOT more money just to keep milk in the house.
