It seems as though Best Buy is wanting to get in on this whole USB-C hub/docking station thing. Apple did release a new USB-C adapter for select Macs and iPads, so this could be their way of trying to get in on those sales or just trying to tell people that they sell USB-C adapters too.
Either way, you can get this Aluratek USB-C adapter from Best Buy for $29.99 for today only. It will work with any Mac and iPad that has a USB-C port.
The port itself has two USB 3.1 ports, an SD card slot and a microSD card slot. This is good for those who need to transfer files, documents, photos or videos onto another computer or device.
The sale, again, is for today only and can be purchased online or in Best Buy’s retail stores. Make sure to get it while you can because this is a pretty good deal for USB-C adapters through Best Buy, not to mention that your Mac will likely thank you for it in the long run. If anything, it’s a good thing to have just in case you need it.
