McDonald's Is Giving Away 10,000 Bottles of Big Mac Special Sauce

Attention, Big Mac lovers.

On Thursday, Jan. 26, McDonald's will give away 10,000 bottles of its Big Mac sauce to celebrate its new Grand Mac and Mac Jr. sizes.

The twists on the popular menu item - which features two patties, special sauce, lettuce, cheese, pickles and onions on a sesame bun – offer an even larger and slightly smaller option for diners, McDonald's said.
