In the past few years, McDonald's (and some, but not all, other fast food restaurants) really seems to have gone all-in on the price-discrimination approach of setting list prices high and offering all kinds of discounts if you know where to look. Not that this is exactly some secret but a while back, it was explained to us (by somebody reasonably high up the org chart at McDonalds) is that the sandwiches themselves were money-losers, but that fries and drinks were essentially pure profit. (Thus, the birth of the infamous "super size it!" promotion) They reallllly don't want you going in there and just buying sandwiches.
