Pricing starts from $7.99 for "one DVD disc at a time" service and increases to $14.99 premier pricing, which allows user to have two DVDs rented at the same time - and to use Blu-Ray instead of DVDs. Netflix has revealed in its latest financials that a whopping 2.7 million people in the United States still use the Netflix's DVD.com service.
The reasons behind the decision for some people to stick with DVDs rather than jump the streaming service bandwagon are actually quite logical. In rural areas of the United States, there are still large areas where you can't get a fast-enough Internet connection to watch streaming content - or it simply costs too much.
But the other reason to pick DVD rental service over streaming version of Netflix is simply the depth of a content. As streaming wars loom, with Disney+ launching soon, Apple starting its own service and Amazon already competing against Netflix, meaningful online content is nowadays spread across several different services. And at the same time, Netflix's DVD service has almost everything ever produced on DVD, no matter what studio has produced it.
Thus, for those wanting to have the biggest movie catalog to select from, none of the streaming services can beat the DVD rental version of Netflix.
P.S. There used to be similar services in Europe, too. Largest of them was LoveFilm which was eventually acquired by Amazon. The company stopped its DVD-by-mail service in 2017.
