In the delivery date section click Edit Pickup (or Change to Pickup when the date is currently a delivery). This button appears only when Business: General > Allow Pickups is Yes. If your location has more than one active pickup point a modal lists each one with its address and price and a Select button; if there is exactly one pickup point the change is applied immediately. The date's method becomes Pickup with the chosen pickup point. Delivery-related fees already charged are not recalculated.
