First post, please don’t be too harsh.
Used my ‘free coffee’ coupon from the McDonald’s App in store at a kiosk and the option came up for the drink plus the new keep cup included.
Used at McDonald’s Midland WA, and the manager honoured the receipt, but took it before I could get a photo. Did get a photo of the instore self service kiosk.
Good luck!
I can't seem to find the keepcup option on the app, where is it exactly?
