Ask HN: Prescription Bidding

Wondering if this has already been tried or a service like this exists.

1. Patient ask doctor to send the prescription to say ePharmacy. 2. ePharmacy hosts a bidding platform for other pharmacies to bid for cheapest meds. 3. ePharmacy selects a winning bid and sends the request to the pharmacy to fulfill and ship the meds.

Would love to hear folks with experience in the related area to share thoughts - what are the issues - regulatory, technical, business related - has this been tried. examples. - advice or thoughts if this were to be attempted.

thanks!
