Recently, McDonald's made its famous Special Sauce available for purchase by the bottle. But before you get your hopes up Big Mac fans, there's a catch: The bottles were only sold in Australia, and there were only 4,000 bottles available, for a limited time. And that "limited time" turned out to be 15 minutes, because that's how long it took them to sell out.

Of course, it didn't take long for the "secret sauce" to end up on auction sites like eBay, with prices surging upwards of $100. (This is actually the second time McDonald's has sold a limited run of Big Mac sauce in Australia; in 2014, the company auctioned off limited-edition bottles on eBay, with bids starting at $18,000, to benefit Ronald McDonald Charities.) But as delicious as the sauce may be, spending that kind of money on condiments isn't really in our budgets—especially since the sauce isn't really a "secret."
