An anonymous reader quotes a report from Bloomberg: Amazon.com Inc. is almost certain to enter the business of Selling Prescription Drugs by 2019, said two analysts at Leerink Partners, posing a direct threat to the U.S.'s biggest brick-and-mortar drugstore chains.

Amazon has a long standing interest in prescription drugs, an industry with multiple middlemen, long supply chains and opaque pricing.
