I placed my first order last November. The process is exactly as I was told. I emailed my information, and sent original copies to them. Every time I have refilled my medication the representative has been friendly,and knowledgeable. I called today inquiring about the current status of a refill. After a short time, the representative gave me the information I needed (so I wouldn't worry). I appreciate the savings, and the professionalism shown by all the employees I've had contact with via phone. Keep up the good work.

Like most other people, my prescription was very expensive and not covered. I started looking and found this pharmacy. While it takes approximately a month to receive your script, it's worth it for the savings.

In the past, I had heard people talk about getting some of their prescriptions from Canada due to the high prices in the US. I never really considered it until after a local doctor suggested RX Connected for one of my recommended medications. The price for the medication here was very expensive and not covered by by Medicare drug supplement plan. I'm very grateful that he told me about RX Connected. I have since told several other people about RX Connected. After your doctor writes the initial prescription, you just send it in, and the process begins. They are careful, professional, and send me my medication by mail, on time, like clock-work. Thank you RX Connected!
