Amazon's rival Walmart, which currently offers pharmacy services, also has a storefront for HSA and FSA products.
The company also acquired an internet pharmacy company, PillPack, in the summer of 2018, signaling an interest in adding prescription medicines to its marketplace. It now has a leader for that pharmacy business, a veteran who helped build Amazon's Kindle self-publishing platform. But PillPack, which primarily serves older customers who take multiple medications, hasn't been fully integrated into Amazon and still operates independently.
Prescription drugs is a notoriously challenging product to offer, given the complex web of intermediaries that sit between the drug manufacturer and the pharmacy. To sell prescription medicines, Amazon will need to work with middlemen, known as pharmacy benefits managers, in order to take a customer's insurance.
Some health experts suggest that the move into adding HSA and FSA cards is a smart method for Amazon to learn more about people's spending on health.
"It's a back end way for Amazon to learn about consumer purchasing behavior of health care products and services, as it moves more deeply into the space," said Michael Yang, a health-tech investor with Omers Ventures.
