I guess it's the start of this year's equivalent of the McDonald's November deals, the first weekly deal is a Big Mac small combo plus a Cheeseburger for $6. Redeemable via app only, one offer per person.
McDonald's is also giving away free 6 pack Chicken McNuggets on Wednesday, 17th November. However for some reason McDonald's won't let me take a screenshot, so here's a photo from another phone. Expired.
