Oculus is slashing $200/£200 off the price of the Rift and Touch bundle for a limited timed.
Available beginning today, the bundle gets you the Rift headset, two sensors, and two two Touch Controllers for just $400/£400. The offer will be available for the next six weeks, but more importantly, you can get it at a number of participating retailers, not just through Oculus.
The bundle does not come with any games. Although it's currently matching PlayStation VR's price in the US, Sony's headset is still the cheapest option in the UK. That's obviously not taking into account the cost of a decent PC you'll need to power it.
Assuming your PC is solid, $400 is a small price considering how new the tech is.
