We'll keep this one simple - McDonald's Australia is doing $1 Big Macs today only - June 25.
To cop the tasty offer, you'll need to register if you haven't already signed up to the smartphone app, then go to the homepage, where you can find it under the 'My Rewards' tab.
From there, simply redeem your offer by scanning a QR code at the restaurant or add it to a mobile order. To our knowledge, only one redemption can be made per account. Enjoy!
