McDonald’s is making that very (not) secret, heart attack inducing sauce that has adorned the insides of the Big Mac for years available to US customers. The special concoction has been sold in very limited runs over in Australia and on eBay where a single bottle climbed to as high as $15,000 before it was sold. While this will be the first time US customers will have a chance to get some of their very own, it isn’t going to be easy. Availability will be very limited and the eBay listings that are bound to start popping up anytime now surely won’t be cheap.

Ronald McDonald is only going to have 10,000 bottles of the special sauce available for the entire country. It will be giving them away in restaurants across the US and through its social media accounts in celebration of the upcoming new Grand Mac and Mac Jr. variants. It is an 11.4-ounce bottle and the golden arches won’t be letting us know which locations will have it until tomorrow.

We will update this post when more information is available. You can take a look at the teaser video right here.
