I love your service! I recommend it to anyone I hear, like me, is taking "Cadillac" medications. Your "price match" guarantee has saved me oodles, as has the shipping I bought that makes it "free". I could not afford my medications if I had to pay otherwise, even with my insurance for medications, your service is vastly less expensive.
