Amazon offers the Dell Thunderbolt TB16 Dock for $224.98 with free shipping. That's the lowest price we could find today by $10, although we saw it for $30 less in May. It includes a 240-watt AC adapter and features two USB ports, three USB 3.0 ports, a Thunderbolt 3 (USB-C) port, HDMI, DisplayPort, mini-DisplayPort, VGA, Gigabit Ethernet, and audio jack.
