Little bit early, but might as well share.
Two small McChicken meals for $8 via the app, only available on Saturday 13th June.
Starting Sunday 7th June until Saturday 13th June is also $1 large fries, but in my opinion, not as good as the $8 meals on both Saturday 6th and 13th June.
Edit: Fixed a date error
Why are these only 1 day - and always Sat??
