For best prices, high quality medications, referral site is Big Mountain Drugs
It depends what medicine you are looking for.
I tried a few times to buy Finax and Finpecia for my husnband, and a couple drugs for myself on http://med-pacific.com. The representatives are nice and they were willing to answer questions about my order. I believe they ship medications all around the world.
From my last order, I got a coupon code to have $5 off. Hope it helps you guys saving a few bucks.

never heard Big Mountain but I have used a European site called the-drug-store.com and i have been very happy with their prices, quality, packaging and delivery.
