One man's trash is another man's treasure. Maybe trash and treasure are too strong a words. Let's put it this way, frugal individuals are always on the lookout for good deals. My wife's immediate family are a perfect example of this mindset.
They absolutely love going to flea markets and yard sales. They can spend a beautiful summer evening driving around, perusing over all the items available to quibble and barter over. That is definitely not my preferred way to spend a beautiful afternoon, although I have found sports memorabilia and firearms over the years that have peaked my interest.
