September 29 is National Coffee Day, and Tim Hortons is celebrating with a new app offer in Canada!

Now through October 5, buy a coffee on 4 different visits and you’ll earn 400 bonus points! To get the points, make sure you’re signed up for the Tims Rewards program — you can sign up online or through the Tim Hortons App for iOS and Android.
When you redeem 400 Rewards points, that gets you a free Brewed Coffee, Tea, Dream Donut, Filled Ring, Dream Cookie, or Baked Good.
This offer is valid at participating Tim Hortons locations in Canada through October 5. You’ll need to separately purchase the 4 coffees in different transactions to get the bonus points. The offer can only be redeemed once per account.
