I often hear that Shoppers Drug Mart is too expensive to shop at, even when you include Optimum points into the pricing, but 20x points days are the way to save and dlee cleaned up at the most recent 20x day.
Forum member dlee bought $54 worth of stuff (see the regular points, that is a great way to know if you have spent enough or if something was not valid for points, it needs to be 500+ for promos where you need to spend $50). She then brought down her total with coupons, a promo card from a previous week (if you redeemed your points in the West, you got $15-30 back on a promo card). dlee is lucky, my store will not enter FPCs as 2001 for promo days, but many stores will.
Click here to see what she bought and how she brought down her total to less than $50 and see the receipt to show that you really do get points when you use coupons to bring the total under $50
