If you're just reheating a cold meal why am I going to pay you to do so and deliver it instead of buying one at the grocery store instead? I also own a microwave, a freezer, and an oven.
There's a difference between chilled meals(which last 3 days), and frozen meals(which you find in the supermarket). Munchery sold chilled meals, and at least according to reviews/media, they we're quite good.
