This seems flawed in that you're encouraging companies to produce milk that lasts longer above all else. I'd rather they prioritize quality. If there's a brand that tastes better to me, I'm likely to buy their milk over milk that lasts longer. My impressions of how each company treats their livestock and the size/locality of the company plays a part, too, but my knowledge there is limited. To ensure it doesn't go bad, I purchase in smaller quantities. I'm unlikely to buy a full gallon of milk at once.
