Thank you for your effort. I have the Canadian Michaels coupons which are great but I shop in the US (I live very close to the US border) and I used to be able to get the coupon which are good in the US stores. When I google for Michaels.com I still get the Canadian ones. They seem to have blocked Canadian IP addresses from getting US coupons and this has just happened.
I am even registered in the US for Michaels Rewards.
