I cannot state my Shoppers Drug Mart source, due to the fact that this information has only been shared to employees at or above a specific level - but I have direct knowledge that Shoppers will be holding their Mega Redemption on December 1st. (I do not know if it will extend to December 2nd as well).
For the 95,000 point level, you will get $250 in redemption money. I don't know about the lower tiers, just the top tier.
Save your points!
