Just received this offer in my app, so it could be YMMV. I am in the GTA.

Have this offer for buy one get one free for any hot beverage purchased in the app. The offer is on all my accounts (I made a few for the Big Mac deal a couple of years ago).

Just wanted to give you guys a heads up to check the app. Holiday drinks are included as well as all sizes of drinks as far as I can tell. Cold drinks are not included.
