Take advantage of the offers!

I downloaded this app to get a free fry and drink with the new signature sandwich. Turns out I used that offer more than once already and another one. Plus a offer to get one signature sandwich get one free using the offer on the app. Point is. I feel like Im robbing McDonalds with this. The offers change, but so far no problems. Im very impressed ??
