Amazon is considering new standalone subscription programs in grocery and healthcare, and potentially integrating One Medical's primary care service with its Prime membership program. The company aims to launch these services by the end of the year. However, these plans could change or get canceled. The new subscriptions are a hotly debated topic internally, as adding new healthcare or grocery benefits to the existing Prime program could raise the membership fee, potentially making it too expensive for some users. Amazon's subscription revenue grew 13.5% to $9.89 billion in its most recent quarter.
