Best Buy.com has Insignia Dock Kit for the Nintendo Switch (Black; NS-GNSTD19) on sale for $34.99. Select free in-store pickup to save on shipping, otherwise, free shipping on orders $35 or more. As far as I can tell, this hasn’t been on sale since January (at this same price).
Note, availability for in-store pickup may vary depending on location.
Includes:
- Insignia Dock Kit w/ USB/HDMI Port for the Nintendo Switch (Black)
- HDMI Cable
- AC Adapter
The cheapest thing I could find to make it to free shipping was $.99, but ended up buying something else.
