McDonald’s Big Mac sauce is considered to be one of life’s greatest mysteries… for people who haven’t tried Thousand Island Dressing. Still, people are suckers for memorabilia from the Golden Arches, and fast food chain is using their drug dealer like grasp on the public to do a little bit of good.

For years, McDonald’s has run the Ronald McDonald House, a charitable organization that helps families while they have a loved one in the hospital. Now, McDonald’s in Australia is selling 200 numbered bottles of the Big Mac Sauce on eBay to help raise funds for the organization. So far it seems to be working as the high bid on the bottle #1 of 200 is sitting at a high bid of $23,000.
