The sauce is the highlight of the Big Mac – and we're sure you've often wished you could bottle it up and smother your own burgers and chips with the stuff.
To celebrate the 50th anniversary of the Big Mac, McDonald's have launched a charity auction on eBay, encouraging Big Mac enthusiasts to bid on three 500ml bottles of the exclusive sauce. Not only that, it will also come in a limited edition mini fridge shaped like a Big Mac – pretty darn cute!
Bidding started on Wednesday, May 30th – and the price tag has already skyrocketed to $4000.00.
All proceeds will go to the Ronald McDonald House Charities, which helps seriously ill children and their families.
The auction will wrap up at 10am June 6th. From 10:30am on the same day, 100,000 bottles will become available in Macca's restaurants across the country – while stocks last.
