This is interesting because Amazon isn't exactly known for supply chain integrity. Who here hasn't received fakes from Amazon? If you rely on a specific medication for your health, is Amazon a brand you trust to deliver it? How long until they start commingling pills and shipping random counterfeit/fake product to users? Hope it never happens but if they do with pharmaceuticals what they did with everything else they…
They have lots of different businesses and associated supply chains, they're not going to have random 3rd parties selling prescriptions on Amazon like they do for many verticals. There would be no reason to integrate prescriptions in with their warehouses, so I don't think one is going to change the other.
Do they all ready have a supply chain close to the requirements needed in healthcare ? For what ?
