The mcdonalds $5 meal deal is a scam

you can use the app to get bogo double cheeseburger for $2.89 after tax. wait 15 mins get a large fry for $1, wait another 15 mins get a large drink for $1. so 2 double cheeseburgers, 1 large fry, 1 large drink for $4.89 total. you can also switch one of the burgers for nuggs instead if you want. Also after doing all that you probably have enough credits for a mcchicken
