When is the latest I can cancel my order?

Technicallyyyyy you can cancel your order at any time. However. If you cancel your order after a producer’s window (each producer sets their own. They range but typically aren’t longer than a few hours), you will still have to pay for your order. So, I would only recommend doing this if you absolutely don’t want your order. Or if you enjoy paying for food that you don’t get to eat.
