I hadn't thought of that, thanks. A few minutes ago I thought of working out $ cash-back per $ spend though. If Rexall doesn't offer a double-dip for tomorrow, I won't be shopping there tomorrow. Looks like my best offer is Shoppers today Spend $30 get $8 back. That's .266 cents per $ spent compared to Rexall's .20 cents per $ spent.
Ohh, never mind! I just checked the Air Miles thread and tomorrow will be a double-dip day! Forget Shoppers today. I'm going to Rexall's tomorrow.
Spend $50 and get 200 miles ($20 cash-back). That's .40 cents cash-back per $ spent.
Yes, just once. However, if the offer in the app says "for EVERY $xx get xxx points" then you can double or triple the points as long as it's done in ONE transacation. IE, tomorrow my app says "for every $20 spent get 5,000 points". If I spend $20, I get 5,000 points. If I spend $40, I get 10,000 points. If I spend $60, I get 15,000 points.
