My belief is that you should focus on buying value on the things you enjoy, and you should focus on making big wins to reduce your expenses on non-essentials and things which don’t bring you joy. For example, in our family eating out is a treat.  We save a lot of money by not dining very often.  But, when we do dine out we focus our efforts on nights where kids eat free.  Not only do we save money this way, but if my son decides that tonight’s dinner choice is not high on his list of priorities, we didn’t waste money on a meal.  This takes the financial tension out of any wasted food and allows my wife and I to enjoy the meal more.
It turns out that the German beer industry suffers from small-scale production. There are 1,000 little local beer companies in Germany, shielded from competition with each other because each German brewery has virtually a local monopoly, and shielded from competition with imports. The United States has 67 major beer breweries, producing 23 billion liters of beer per year. Germany has 1,000 major beer breweries, producing only half as much beer per year as the United States. That's to say that the average brewery in the U.S. produces 31 times more beer than the average brewery in Germany.
