Crush Your Beer Fridge, and Maybe Your Main Fridge, Too.

In 2022, I wrote a blog about how that old beer fridge you might have lurking in your garage is probably worth replacing with a newer model. In short, refrigerator prices have dropped, and efficiencies have increased to the point that replacing an old beer fridge can pay for itself in just a few years.
