I too got the email.
The message seemed to indicate that Acme was offering some specials for Halloween in the way of "tricks and treats"
The trick was the Flexvolt microwave. I took that to mean that the next time we see it will be on 4/1/18 as an April Fools joke.
A 600 Watt DC microwave using a 60V battery would seemingly draw 10 Amps - so maybe it could be doable - but I think it was a Photoshop joke
