Shoppers Drug Mart 20x day

This saturday, Jan 2nd shoppers drug mart is having one of their 20x points days. The way i make these work is to use as many high value coupons as possable so they are paying me to take home the items. There is a motrin $5 coupon out. the regular price of motrin is 5.99 so you get 20x points on 5.99 even tho you are paying .99. I usually only get things at Shoppers if they are a really good deal and i need the item. I used to stock up on coffee on shoppers 20x points day and milk, but i am overstocked on coffee at the moment after Melitta's deal a couple monthes back. ( each tin was .47, plus a free large tin for every 5 you bought- so i have a ton of coffee to use plus FPC's for next year)
With shoppers 20x points day, if you can manage to use enough coupons to but your bill in half you are essentially getting enough points to make your items free. ( 40k points on bonus redemtion days are woth $100) So if you total before coupons is $100, after coupons is $50, you will get back 20k points, worth approx $50 at the highest redemtion level. That is where the motrin coupons and other high value coupons come into play. Say if you got 10 motrin at 5.99, used 10 coupons, that is $59 before coupons but only $9 after coupons (plus tax) you would get full points on $59 but paying out of pocket $9. Then add to that items that you would buy anyways, milk etc and they are actually paying you to take home the items through points. :) Hope this all made sense. :)
