Amazon's Echo Show 5 falls to $40 in smart display sale

Amazon's Echo Show smart displays with Alexa voice control are already a good value next to the competition, but a big smart display sale is making them even cheaper. The Show 5 is the least expensive, on sale right now for just $40, or 53 percent off the regular price — a great deal for Alexa capability with a display. And if you need a larger screen, the Echo Show 8 is priced at just $60 (54 percent off) and the Echo Show 10 is $160, for a savings of 36 percent.
