Prime Big Deal Days is the autumnal version of Amazon's big summertime Prime Day sale and the perfect way to get a big head start on holiday shopping. In addition to other benefits, including faster and cheaper shipping, access to Amazon Prime Video and Amazon Music, Prime members can also take advantage of sale prices even earlier than Prime Big Deal Days, which takes place October 7-8. Many of these early-bird deals are for Amazon devices, which include Echo smart assistants, smart home security cams and doorbells, sound bars, and Kindle e-readers. Some marked-down products aren't built by Amazon but instead include Amazon software, such as smart televisions with Fire TV as their platform. Here are some of the cheap TVs Prime members can purchase for over 40% ahead of Prime Big Deal Days.
