Saturday February 23rd and Sunday February 24th Shoppers Drug Mart is having a bonus Optimum point redeem event.  From the email they sent me it looks like you have to redeem for cosmetics or fragrances. 

 Small print on email:

Taxes are payable on the full purchase price prior to the application of the discount reward. Offer is a reduction off your total pre-tax purchase price of products eligible for point redemption.  All other reward levels remain in effect during this promotion.
