I usually purchase 1 gallon containers of skim/fat free milk. I'm finding it more common for it to be within several days of the sell by date, too close for my liking. Today I opted for two 1/2 gallon containers with a date of March 21 vs. a gallon with a March 11 date. But I hate the idea that this will likely contribute to a gallon of milk having to soon be discarded. Interested to hear others' thoughts on how the dates affect their purchasing.
