Your website can show a See what days we deliver to your area button (enabled per module in Client Config, e.g. A la Carte: Show "See what days we deliver to your area" button). It opens a window where the visitor picks a State and types a Zip Code. Sprwt looks the zip up exactly like the cart does and replies with the delivery days (and catering days) of the matching route and the delivery fee (Free when $0). If there is no match, the visitor sees Unfortunately we do not deliver to <zip> in <state>…, any pickup locations in that state with their pickup days, and a Name/Email form to be notified – which feeds the Requested Zip code Updates list. Unmatched searches are logged under Requested Zip Codes.
