Today (January 23, 2012) is the day that Tim Hortons introduces their new 24oz extra large cup. See this handy picture below to see what size your cup order is now.
Trust me, the new 24oz is way too much coffee. Our Tim Hortons made a mistake and gave us the new extra large last week when we ordered our extra large coffees. We drink coffee all day every day and found this to be too much coffee.
