Price and value are not the same things.
Buffett is notoriously frugal. And frugality is all about value.
Price is what you pay; value is what you get. Frugality isn’t about buying anything at a low price. It’s not about paying a lot for something just because it’s valuable, either. it’s about buying value at a low price.
The key to making a smart spending decision isn’t just price; it’s value, too. So when you’re getting a deal, calculate value into the equation.
