McDonald’s Offers $1 Big Mac with $40+ McDelivery Orders via App until 18 January 2026

To redeem the deal, just open the app, go to the Rewards & Deals section, and apply the $1 Big Mac offer to your order. Once your cart hits the $40 minimum (before fees), the discount will automatically kick in, reducing the iconic Big Mac to just $1.
How It Works — Fees Still Apply
While the offer slashes the price of the Big Mac, don’t forget that delivery and service fees are still part of the deal. There’s a $0.99 delivery fee and a 5% service fee, so factor those into your total cost. Still, with the Big Mac usually priced at $10.75, you’re saving nearly ten bucks, which makes this a strong bonus for anyone already placing a larger delivery order.
Whether you’re feeding the household or stocking up on favourites, this offer rewards those bigger spends with a serious burger bargain.
Offer Runs Until 18 January 2026
This deal is valid for a limited time only and must be redeemed before 18 January 2026. It’s for delivery orders only and only through the MyMacca’s app, so make sure you’re set up to order that way. If a Big Mac is part of your go-to order, this is the time to grab one for next to nothing.
