Sport Chek had a Family & Friends sale like last week, so everything was 25% off (which was the time to buy). Though, if you sign up for their e-mail newsletter, they will e-mail you a 10% off coupon which you'd be able to use. I doubt there are places cheaper, so Sport Chek seems like your best option. Plus they have a good price adjustment policy, up to 1 or 2 months I believe. Otherwise, I can't think of another sporting goods place that would be a good spot to get Jays jerseys. Maybe National Sports? I'd stick with Sport Chek.
