Im very excited about the rumoured 20x the points on March 26. I have a question though. Yesterday I got a 10 GC from shoppers as part of their promotion. How can I use it on 20x the point. For example will it be treated like a coupon (so for example if I buy $50 I pay 40$ and STILL get the points)? or should I buy 60$ and pay 50$ just to be sure to get the points
