Dave Ramsey Admits to Making This Common Costco Shopping Mistake. Are You Making It, Too?

Costco is well-known for offering high-quality Kirkland products, as well as for providing both store-brand and name-brand items at a great price. This mistake is so common, and so easy to make, that even finance expert Dave Ramsey has admitted it's happened to him. "To this day, if I'm not careful, I'm still bad about buying things I don't need -- or too much of the things I do need -- in warehouse clubs," Ramsey said.
