You may be able to pay with lovin’ at McDonald’s these days, but that still won’t get you a bottle of their limited Big Mac sauce.

The fast-food chain has finally bottled their famous sauce, but you just won’t be able to buy it in the United States — at least not yet. McDonald’s Australia, or Macca’s as they call it down under, is exclusively selling over half a million of 25ml bottles until they are sold out. 

If you’re feeling you must absolutely have your hands on this finger-lickinly delicious condiment, one of 200 500ml bottles is already being auctioned off on eBay for the totally reasonable amount of $18,000 USD. But don’t worry, proceeds will go towards Ronald McDonald House Charities Australia — a non-profit that provides support to ill children and families. 

If you don’t casually have $18,000 lying around, you can always try your hand at making the sauce too, but no ill children (other than maybe your own kids if they eat too much Mac sauce) will benefit.
