Amazon may be snatching all of the attention this week with its Prime Day sales, but Microsoft is throwing its hat in the ring as well for anyone looking to pick up a Surface Device. For the next two days, you can snag a free Surface Dock when you pick up at Surface Laptop or Surface Book 2 at Microsoft.

To recap, the Surface Dock usually costs $199.99 and adds a slew of extra ports to your Surface device. In all, the dock includes two Mini DisplayPorts, one ethernet port, four USB 3.0 ports, and one audio out port. Connecting via the Surface Connect port, the dock also operates as a power brick for your device.
