After more than a year of testing, Tim Hortons will launch its new loyalty program across Canada on Wednesday, giving the company a new tool to fend off challenges to its coffee supremacy. The rewards program is centred on visits, which must involve a purchase of $0.50 or more, and can’t be within half an hour of each other. After seven visits, customers get a free coffee or tea at any size, or a baked good (except Timbits and bagels). Instead of a paper card, the rewards program will be offered on the Tim Hortons mobile app as well as on a plastic, reusable swipe card — giving Tim Hortons a wider window into customer buying habits — Financial Post
