Prepping supplies ought to include OTC meds and dietary supplements as well.
The best deals I have found are at Swanson Vitamins. They have good quality, often single ingredient supplements (if that’s important for you) and you can usually have them in a couple days.
Considering what the entrenched government is trying to do to us in regard to destroying our health, and what with supply chain issues, having at least a good multivitamin should be close to the top of everyones prep list. They seem hell bent on denying us anything that might even be remotely good for us.
