Amazon SparkAmazon Spark is a feed that can be accessed by clicking the Spark tab in the Amazon app. It’s like a shoppable feed of stories and photos for Prime members. Think of it as a kind of Pinterest in reverse. Rather than pin things you find around the web to store on your personal page, Spark lets users share photos, tag the Amazon products displayed within, comment on them, and ultimately buy. Spark has also been integrated into Amazon’s Interesting Finds page, so users can ‘heart’ their ‘finds’ and from then on view ads more specific to their tastes.
