Mrs. Fields Cookies - $1.88/pk @ Shopper's Drug Mart (June 7-8)
This is for the milk chocolate and semisweet only, the white chocolate were not on sale.
Each bag contains 8 individually wrapped cookies, $5.49 normal price IIRC.
Not sure if this extends to other SDMs. (Edit: Other RFDers confirm that this is widespread for Jun 7-8.)
