Overview
- Major chains executed National Cheeseburger Day promotions as planned, which peaked on Friday, Sept. 18, with many offers available through apps or loyalty accounts.
- McDonald’s gave MyMcDonald’s Rewards members a free Double Cheeseburger with a minimum $1 in‑app purchase and limited one per customer at participating locations.
- Burger King ran a Royal Perks week from Sept. 14–20 that culminated in a free Bacon Cheeseburger on Sept. 18 with a $3 minimum purchase for loyalty members.
- Smashburger offered any single Smashburger for $1 to SmashRewards members at participating locations while other chains ran one‑day or short‑window deals.
- Most promotions required prior enrollment, were limited to participating restaurants, capped per person, and often excluded third‑party delivery, a setup that boosted app signups but left access uneven for consumers.
