But there's an east trick to save a couple dollars while still getting the taste of the iconic burger.
Just order a McDouble without ketchup, then add lettuce and Big Mac sauce. This will cost about $1.49.
The McDouble is part of the Dollar Menu & More. It comes with two beef patties, a slice of American cheese, pickles, onions, ketchup and mustard.
But by eliminating ketchup and adding lettuce and Big Mac sauce, you're going to get something very similar to the Big Mac.
You'll just miss out on the sesame seed bun and extra slice of bread between beef patties.
The blog A Hamburger Today tested this method and weighed the two sandwiches.
"Aside from that extra middle bun layer, the amount of food you are getting between these two burgers is identical by weight," the blog writes. "It's possible that the Big Mac has an extra-light bun and more toppings or vice versa, but the quantity of toppings seemed pretty much identical."
