UPDATE: It was indeed a mistake, and the extra $5 coupon is now gone. You can still use the promo code below to cut the price to $28.89, or $7.22 per plug.

EARLIER: When Alexa and Google Assistant-enabled smart plugs drop down into the $7-range, it’s a no-brainer. Buy them. Similar products from big brands sell for between $20 and $30 a piece, and they do the exact same things. Today, however, we stumbled upon a sale with pricing so good that it has to be a mistake. The popular Amysen Smart Wi-Fi Plug 4-pack sells for $33.99 on Amazon, which is already a great price — but there’s a $5 coupon right now on the product page that cuts it to $28.99. But wait! Use the promo code KYSCVKIE at checkout and you’ll cut the price all the way down to just $22.19. That’s just $5.55 each, which is absolutely unheard-of. In fact, it’s almost definitely a mistake so you’d better hurry up and take advantage of the deal before Amazon fixes it!
