Are you saying that equals a Big Mac? It doesn't equally, but for sure when those McDoubles go on sale for a buck, adding the sauce and lettuce would save some serious dosh.
Any McDonald's I go to charges like 80 cents for Big Mac sauce. I finally learned to start asking for it on the side. If you get it on the burger they give you like 3 drops, even if you emphasize extra. If you get it on the side they give you enough for like 2 burgers.
But that is still a great savings. Even at .80 for the sauce, and maybe .40(?) for the lettuce, you get basically a Big Mac without the extra bun for Less than $2.50 on those $1 McDouble deals. Actually, was looking at their website just now, haven't been to McD in at least a year. Did they get rid of the $1,$2,$3 menu?
They expanded it to compete. Fries, drinks, burgers, chicken sandwiches, breakfast, I think ice cream.
Hah, went to their deals page...Turns out today is National French Fry day. Free medium fries for everyone with their app.
