I feel ashamed. I only skimmed the menu and didn't see the 2 for 2.50 menu, but very well may have missed it. I paid 1.99 for the mcchicken and 2.69 for the double cheeseburger IIRC.
I also got sucked into getting the McFlurry because I remember liking the Rolo one ~5 years ago, this time I was kind of underwhelmed. If I had just stuck with my plan of caramel sundae, extra caramel that would have knocked off another buck I think too.
