A Canadian Tradition

Every year, we Canadians look forward to the annual Tim Horton's Roll Up the Rim event.
This year was their anniversary ( I'm not even sure which one ) but I DO know there were TWO chances to win on each cup.

I'm not an excessive Tim's visitor but I am addicted to my morning coffee which I pick up on the way to work. They say that the chances to win are one in three so I thought it would be interesting to keep track. So here's the TALLY:
Purchased 47 cups of coffee- won 9 coffees and 5 donuts. Pretty close to 1 in 3 chances of winning.

I think the contest is drawing to a close. Yesterday, I got a plain cup. SO disappointing but it's another sign that spring is a little closer.
