First off, McDonald's has an online store? You learn something new everyday.
Coming soon to a home near you are six scented candles that the burger giant will release and when you have all of them together (and lit) they will create the smell of a delicious McDonald's Quarter Pounder. (insert drooling emoji here)
Better set a notification for this, McDonald's says they are releasing a limited quantity and you need all six to make the the smell compete (kind of like the Infinity Stones). Unless you are an odd duck and don't like pickles in your burgers.
