NewEgg has the Oculus Rift S headset/controllers for $349 with free shipping.
Note that the Rift S requires a computer with DisplayPort. Check your graphics card for VR support before purchasing.
Edit: This matches the Black Friday price at Best Buy and Lenovo. (Maybe more places.)
Forgive any mistakes on this post. I'm posting from the mobile app. (And the mobile app returned fewer results than desktop.) Happy Thanksgiving and happy shopping!
