For 2 days from 10:30-22:30, McDonald's are doing one of their app deals, Cheeseburger Small Combo + Cheeseburger for $6. Maybe not that great but it's been a while since they've had deals for non Uber purchases given the lock downs.
Other than this deal their app still seems to lack any deals except for the McCafe rewards loyalty thing (5 coffee, 1 free) and feedback offer
