Maybe I’m misunderstanding what you saying but why would you want 3 crockpots?
It's more like a buffet setup. Three separate cooking chambers connected together. I'd love one, but there's no place in my home to store it. I'd use it for soup night: chili, potato soup, and a vegetable soup all cooking at once. Or dips like baked crab dip, spinach dip, and a cheeseburger dip. They'd be cooking together, but separated.
