McDonalds is still super-cheap if you make efficient use of their deals and coupons in their app.
You can come across good deals once in awhile, but it certainly does not come out to super-cheap (except perhaps the breakfast deals). The problem with the app deals is that you can only use one at a time. They replaced their dollar/value menu with these so-called deals. When they stopped selling $1 sodas last year, they replaced it with an app deal. So, you used to be able to use a deal for whatever you wanted and get a soda for $1. Now, you have to choose one or the other, which means you're paying more.
