McDonald's has put their Big Mac special sauce for sale before, and now they're doing it again.
The sauce will be available at select locations and the proceeds from the sale of the sauce will go towards the Ronald McDonald House. Now there is a catch, the sauce will reportedly only be available for sale in Australia but lucky for us there's eBay!
While McDonald's is selling the sauce don't think you'll be able to make it on your own.
The ingredients are on the bottle, but how much of the ingredients you'll need remains a mystery.
