Many of us have experienced the luxury of pushing a Target shopping cart. Compared to shopping carts at other stores, they feel like they're floating through the store, gliding smoothly around corners.

Recently, I had a shopping trip where my cart only had 3 wheels. I didn’t even notice until I took a quick turn in it and it felt weird because of all of the stuff I had in the cart. The rest of the time, it didn't tip or try to rest its weight on the missing wheel. It just worked. Wild.
