Two words: free shipping. Clever young Well.ca is the largest Canadian non-prescription online drugstore. Along with drugstore standards from vitamins to makeup to over-the-counter meds, available skincare lines include Cliniderm (for sensitive skin), Juice Beauty, Kiss My Face, Derma E, Burts Bees, and Green Beaver (Holly, they carry For My Sister Deodorant -- see comments below!). And the company ships free within Canada.
