On Delivery settings > Delivery areas & pricing choose Generate from a radius (about 1 min, we build the list):

1. Pick the Country – United States (5-digit zipcode, radius in miles, default 20, max 200) or Canada (first 3 characters of the postal code, radius in km, default 30, max 300). Choosing Other disables the form and points you to the spreadsheet import, because Sprwt only has location data for those two countries.
2. Enter your Kitchen zipcode (or postal code) and the Radius, then press Generate zipcodes.
3. Sprwt lists how many zipcodes/districts it found and shows two starter price bands (Distance from your kitchen → Delivery price, e.g. 0–10 mi at $10 and 10.1–20 mi at $15). Edit the from/to distances and prices, use + Add another band, or remove a band with × (at least one band must remain).
4. Press Save pricing (or Start over to change the radius).

Every zipcode in range is saved with the delivery price of the band it falls into, for the selected kitchen. Validation messages: Each band needs a "to" distance greater than its "from", Give every band a delivery price above zero, Nothing found in that range. Try a wider radius, or use the spreadsheet import. This lookup does not use AI or credits.
