Ocean Technology via Amazon offers the Unitek USB 3-Port Hub and OTG Docking Station, model no. Y-2175, for $21.49. Coupon code "WGGMQJNY" cuts that to $9.24. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $8.22.) That's tied with our mention from two weeks ago, $37 off list, and the lowest total price we could find. It features three USB ports, one Ethernet port, and compatibility with Windows and Android devices.
