The Amazon Echo Buttons are on sale for $14.99 for Prime Day. This is the first time the 2-Pack has ever been on sale, so this is the lowest price we’ve ever seen. Echo Buttons pair to any Echo model and serve as input devices to interact with special Alexa skills. There are currently 40 Alexa skills that are compatible with Echo Buttons. As you’d expect, most of them are games, such as Simon and Trivial Pursuit. Echo Button skills got off to a slow start but have been picking up steam lately with several new releases in the last few weeks. The Echo Button product page is advertising a deal that saves an extra $10 off when you by a pair of 2-packs, for a total of 4 buttons, but it is taking $10 off the regular price, so it doesn’t save you any more money if you buy a 4-pack instead of a 2-pack.
