Since I never go to Wal-Mart and the nearest Costco is 200 miles away I reckon I'll never see them.
Well, don't rule it out, one thing about the business world, if something catches on, it spreads to other areas. So, if it goes over well at Wal-Mart and Costco, I expect other stories (Target, et all) would copy it.
I don't know why we don't go back to the old cardboard milk cartons, bio-degradable and eco friendly. Unlike the plastic ones which last forever and are made from petroleum. Tiny little paper cap and recycle the rest.
Well, they still have those for half-gallons. Did they ever use them for a full gallon?
Hell what was wrong with the glass ones?
Dunno, although it does have this annoying habit of breaking when you drop it. Also, I doubt mass manufacturing of glass is cheaper than the alternatives.
