Surge Pro Store via Amazon offers the Ntonpower 3-Outlet 3-USB Donut-Shaped Mini Power Strip in Black for $21.99. Coupon code "63BIDA3T" cuts that to $15.39. Plus, Prime members receive free shipping. That's tied with last week's mention, $30 off list, and the lowest price we could find. It features three 2.4-amp USB smart-charging ports and a 15" wrap-around cord. Deal ends October 16.
