Looks like this microwave hasn't been sold (as new) on Amazon since May 2022, using CamelCamelCamel to look at the price history of this item (B07894S727), being last sold at $75. However, there are four other Alexa-enabled microwaves currently being sold on Amazon, for $143, $144, $300 and $2197.

I wonder how long the Alexa integration will last. I suppose even if the Alexa integration is discontinued in the future, they would still continue to function no worse than regular microwaves.
