They're pretty much eliminated the Dollar Menu too. Even after the main menu items were gone, I'd go with the kiddo and 4 pc Chicken McNuggets were $1 at most locations around here.
There was even a time when the app deal specials were really good. Like $1 for an sandwich once a day, including the then new fresh Quarter Pounder with cheese. Then that deal changed to once per week, and then went away. The last time I saw anything that seemed worthwhile was maybe the BOGO . But then I've gone on the road and the local deals were way better. The best local deal I got (ended about 6 months ago) was $6 for any Quarter Pounder meal, which included the Smoky BLT Quarter Pounder, which was typically $7-8 on its own.
I think it was working OK when not too many people were using the app deals, but after a while I'm thinking stores were complaining.
Even then, there's an a la carte price for beverages that's pretty reasonable. It was 99 cents for any size, but now it's usually $1.29. Might be reasonable with another deal.
