Today’s Tuesday text offer form Shoppers Drug Mart Canada is for 20x the PC Optimum points when you spend $75 or more on nearly anything in the store. This offer is valid today only, and if you didn’t receive it by text you can just scan the bar code from the image here. The offer is a general one and not specific to anyone’s account.
If you need some help reaching the $75 spend, this week Shoppers Drug Mart Canada has Betty Crocker cake mixes and frosting on sale for $2.49, plus there is an in-store bonus offer of 2,000 PC Optimum points for each one that you purchase. If you add as many of these as you need to get your entire purchase to $75, the cake mixes and frosting will work out to be free.
Also, if you are on the hunt for a PS5 these seem to be showing up at Shoppers Drug Mart locations more frequently, so this would be a good item to purchase using this offer.
