The official meross Amazon storefront now offers its all-new Matter Smart Plug (MSS115) for $13.99 after you clip the on-page coupon. Shipping is free for Prime members or in orders over $25, too. Today’s offer is only the second discount we’ve seen so far, and matches our previous mention for the all-time low. It’s the first markdown in well over a month, as well. Learn more in our hands-on review over at 9to5Mac and then check out the details below the fold.
