On the rare occasions I go to McD's, I usually get out for under $4. I guess getting a full-on meal plus an additional sandwich could get in the $12 range, but (1) I don't know why you would do that in the first place, (2) of course, if you are getting MORE than a full meal, it's going to cost more than the standard price, and (3) even so, I'm still not sure how you get up to $12, but whatever.
