What King County publishes for the home cottage-food path
Dollar amounts appear only when we have read them on an official page. If a cell is blank, that office has not published a flat price we can quote. Ask them before you pay. A fee that varies with sales is a percent of receipts (privilege tax / BPOL), not a sticker price. Not MEHKO, commissary, or storefront.
