It may have been 2 years ago or so, but the process stopped working and wouldn't accept my confirmation after giving my credit card info. I've got a handful of privacy tools on my browser. I finally gave in and temporarily white listed the pharmacy and still cleared out any trackers. Sent the web admin a basic, "WTF, folks?" and got a BS non answer.
Fast forward to maybe November or December last year. Refill time, and the trackers were even worse. I kind of need my meds though. So I created a new account on my computer, and ordered my meds.
Then I filed a complaint of a possible HIPAA violation, starting at https://www.hhs.gov/hipaa/filing-a-complaint/index.html and was polite, factual, and provided some non hysterical examples of how a prescription could indicate a specific health issue with resulting advertising or PII release to parties not needing it.
I received an email at the end of February. I was probably not the only person that sent a complaint, but the end result is that KP is being investigated.
Yay.
