It’s undisputedly the special sauce in Big Macs that sets it apart from every other burger – and you can now get your hands on a bottle of it, all in the name of charity.
To celebrate Big Mac’s 50th birthday, McDonald’s is auctioning three 500ml bottles of special sauce – along with a limited edition mini fridge – with all funds going to Ronald McDonald House charity.
To be in the running for the three bottles of the delicious sauce, you need to place a bid on the eBay listing before 10am Wednesday 6 June 2018.

The auction began on Wednesday but bidding has already reached $3,650.
Ronald McDonald House is an independent charity that provides a ‘home away from home’ for families of seriously ill and injured children being treated at nearby hospitals.
