Customers used to hit checkout with no pickup or delivery option chosen — an extra step (or several) before they could order, and an easy place to pick the wrong spot. Now checkout preselects the most likely option for them: the one tied to their CSA subscription, then the option from their most recent order, then the closest pickup location. If they have a saved delivery address inside one of your zones, delivery is auto-selected with the earliest available date and time window. When nothing can be preselected, they get a friendly "Select a pickup location" prompt instead of a confusing error, and the Place Order button stays disabled until every part of the order has a valid choice — so nothing comes through with missing fulfillment details.
