When I moved to Vancouver Island from Ontario, I was disappointed to find that bagged milk is not available here.  It stays fresh much longer than the cartons.  I would open one bag and pop the other two in the freezer.  The washed bags can be used for many things.
The lack of availability should not surprise me as the grocery stores do not know the difference between Yams (which are fibrous and have no sugar content) and Sweet Potatoes (which can be orange or yellow and are delicious.  They originate in two different continents.  The produce managers should all be required to take a basic course in botany.
