In zipcodes 90028, 90038, 90004, 90049 and some more, I cannot find a JAR of mustard on supermarket shelves. I can find plastic, cone shaped containers that make getting the last 3 to 4 ounces of mustard nearly impossible to use. And this problem is across a variety of brands. This is a type of price fixing that the gov't is supposed to control under anti-trust laws. But they aren't. If you live in other than California, and can purchase mustard in 6 to 18 ounce round or square containers, please post with the maker and your state. Thnx.
