In Netherland, the folding crates of Albert.nl, the delivery branch of big supermarket chain Albert Heijn, are very popular. They're sturdy, they fold up, everybody uses them for everything, and the delivery men totally support your right to use them for whatever you like.<p>And albert.nl doesn't lose any money on it, because you pay a 4 euro deposit for the crate. If you keep it, they've already got the money to replace it.<p>So why don't US dairy companies do that?
