It's also very interesting when you begin thinking of how it affects other people's value or money. In his example of bargain hunting and collecting coupons, he spent 8+ hours to save $20, which he realized was a poor return on his money. (That must have been some serious bargain hunting). Not only that, if he purchased some goods for $20 less than he would have without the coupons, then the vendor ended up $20 poorer than he would have. So he spent 8+ hours to effectively transfer $20 of value from the vendor to himself, which is even worse than spending 8 hours to create $20 of new value. It certainly depends on how you view other people's money and value compared to your own.
