I’m a huge fan of Zappos.
I still have no idea why this sort of thing has not been implemented in the online pharmacy era with pre-packaged medications. Unfortunately, laws exist prohibiting this sort of activity with the assumption that this technology isn’t an alternative to real human pharmacists. I’m sure the error rate of Amazon and Zappos fulfillment is much, much less than the 100 steps between a doctor’s handwritten prescription and the patient’s mouth.
