Hello, as a retired USA pharmacist, I can say that Canada Pharmacy Depot has 2 awesome points in my book. Number 1 is the saving cost. If I use my Medicare D plan, I'm into the "coverage gap" in January. It amazes me how over priced the USA system is, sad I have to say that, but it is totally true. Point Number 2 is your customer service. I used to try to go out of my way for patients. I'm definitely glad seeing the staff at Canada Pharmacy Depot embodies that same desire....KUDOS... Paul
