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. The McDonald's at 2225 W Deer Valley Rd and the one at 6535 W Happy Valley Rd were checked on November 5, 2026 and November 6, 2026.
