The pharmacy staff at Cambrian Pharmacy are amazing. I've wasted hours of time at other pharmacies because the staff can't seem to comprehend anything outside of their basic training, but the staff at Cambrian Pharmacy all seem to know how to handle anything (i.e. purchasing vitamin B12, which is kept behind the counter, but doesn't require a prescription).
The store itself has a great selection of natural and organic products, even including snacks, drinks, etc. They also have the best selection of pro-/pre-biotics that I've ever seen.
Although I haven't used these services myself, they have a compounding facility on site, and can make up custom vitamins/supplements etc., which is really useful if you're looking for a good source of holistic/naturopathic therapies.
They are closed on Sundays, but open Monday through Saturday until 8pm (not closed Mondays, as stated in another review).
