[Crest] SDM - Crest Whitestrips Classic - 17.77$ (Reg 38.99)
I was at the Queens Quay-Spadina Shopper's Drug Mart last night where I was surprised to find a pretty deep discount on the regular Crest Whitestrips. They were marked down more than 50% from 38.99 to 17.77. ("Premiums" were 38.99 instead of 46.99). I do not know if this deal is on in every SDM though so YMMV. FWIW, there was only one box left at my store yesterday evening.
