When a customer enters an address on the Uber Direct route, Sprwt asks Uber for a delivery quote from your kitchen address to the customer's address. The delivery fee charged is Uber's quoted fee + the Sprwt fee above quote + the kitchen fee above quote. If Uber returns an error the customer sees it as [code] message. Because the quote depends on distance and time, the price can differ from order to order, and zip-code delivery prices are not used.
