I've always wondered what it means by no purchase necessary so I thought I'd read up on what that meant. Rule 2 tells me:
NO PURCHASE NECESSARY TO PLAY: In Canada, obtain a FREE Tim Hortons contest cup and/or a copy of the official rules, by writing to: Tim Hortons Contest Cup, P.O. Box 9296, Saint John, New Brunswick, E2L 4Y8. In U.S.A., to receive a FREE contest cup and/or a copy of the official rules write to: Tim Hortons Contest Cup, Box 1315, Calais, Maine, 04619-6315. All requests for a Free Cup must be postmarked by May 5, 2007 and received by May 13, 2007. Limit one request per envelope with sufficient postage, while supplies last. Void in Florida and where prohibited by law. No mechanical reproductions of requests permitted. All requests must include a postage-paid, self-addressed envelope.So there you have it. No purchase is necessary but it'll cost you the price of postage (which isn't listed) and is likely around the price of a cup of coffee. No purchase necessary doesn't necessarily mean free. Those are my observation's for today.
