How this was computed. Prices are the current price state: each store's price as read from the chain's own ordering system, refreshed weekly. A store's price counts only inside a sanity band around the item's national typical (half to 1.75 times), which drops placeholder and mis-listed prices no customer could actually pay. One price point was excluded before ranking: a $3.99 Whopper reading that appears at 262 stores, 261 of them priced in a single day's collection (November 4, 2026) — the signature of a collection artifact, not a price anyone could pay. It is excluded above, and disclosed here. The Burger King at 10903 Potranco Rd. and the one at 7400 San Pedro Ave were checked on November 7, 2026 and November 9, 2026.
