SAN FRANCISCO — To get customers to come to McDonald’s and buy new versions of its Big Mac, the chain is giving away 10,000 bottles of its trademark special sauce for people to use at home.
The move is to celebrate the introduction of the Mac Jr. and the Grand Mac, two different-sized variations of the classic sandwich.
The giveaway is a first in the United States.
McDonald’s introduced the Big Mac in 1968. In 1975, the special sauce got its own callout in the signature Big Mac commercial, touting the burger’s components—“Two all-beef patties, special sauce, lettuce, cheese, pickles, onions on a sesame seed bun.”
The bottles will be available Thursday at participating locations nationwide.
With only 10,000 bottles available, McDonald’s has specially numbered each bottle of sauce.
According to McDonald’s Las Vegas, bottles of Big Mac Special Sauce will be available from 11:30 a.m. to 12:30 p.m. at the McDonald’s location on 10020 S. Eastern Avenue. Additionally, the sauce will be available from 1:30 p.m. to 2:30 p.m. at the location on 601 N. Stephanie Street.
Guests must use the phrase “there’s a Big Mac for that” in order to receive a free bottle of sauce.
Tomorrow! Use the code phrase: "There's a Big Mac for that" here:
