Earlier quoted context omitted.
I used to say those same rules for Dollar Tree. I'm not that strict about Amazon, but I decided that I don't trust buying OTC pharmaceuticals from Amazon. Even though I hate dealing with the current vendor, since they're bizarrely incompetent a dozen different ways, I suspect they are at least much better about supply chain integrity.
May I ask which vendor you use for pharmaceutical needs now? I used to use Amazon Pharmacy but then have since gone back to CVS.
So I just use a brick&mortar pharmacy nearby, where the pharmacists/techs almost always vary from good to conspicuously excellent.
I think the profession is generally good and conscientious.
