Trader Joe's smaller parking lots help keep their prices low
What? Here's something I didn't really expect. If you're wondering why Trader Joe's has lower prices than, say, Whole Foods, you can sort of attribute that to their small parking lots. Because of their smaller footprint, Trader Joe's is able to sell more per square foot than other grocery stores which means more savings passed down to the consumer in the end. An interesting trickle-down scenario if I ever heard one.
