I believe Kens Pharmacy cheated me. My doctor ordered a one liter bottle of Wilsons solution for my mrsa infection. When I picked up the prescription at at Kens the bottle said 500 milligrams which is not a liter and they charged me $60. Since I had to take this for a month, I knew I would need refills but I needed a refill in several days for another $60. Then I called around town and found Aeva Pharmacy and they told me a one liter bottle would be $45. So, I ordered it from them and when I picked it up, I realized that their bottle was more than twice as much solution as Kens for $15 less. Also Aeva delivers no matter where you live.
