As a part of Prime Day, Amazon is offering a 30 percent discount on select Ring products, and a 39 percent discount on an eight-part set of Ring products.

Ring, which was acquired by Amazon in 2018, produces WiFi-powered home doorbell cameras, outdoor security cameras, and flood light cameras. Footage captured on these cameras can be posted on Neighbors, a free "neighborhood watch" app that lets people post about crime, safety, "suspicious" people, "strangers," and lost pets.

However, Ring and Neighbors market themselves as a crime-fighting tools only by actively encouraging people to fear their neighbors. And by extension, Amazon positions itself as a company that can uniquely address these safety concerns stoked by Ring and Neighbors. Amazon uses Prime Day as a means of getting people to buy heavily discounted Amazon products that lock customers into their broader ecosystem. In this case, that includes Ring. But there are many reasons not to buy a ring.
