Amazon devices being a hot commidity on Amazon Prime Day isn't anything new, but setting a record is (Amazon did not release numbers). Prices dip down, partly because getting an Amazon device puts you in the Amazon sweet spot. The company can get more money out of you if you need to keep paying for a Prime membership (currently $119 a year) and products to support your device (upcharged Prime movies for your Fire TV, digital reading material for your new Kindle or Amazon Fire tablet).
