If you buy an Oculus Rift and Touch controller combo package ($799.98), the retailer will throw in a $150 gift card. You can then go ahead and use that towards the kind of powerful PC you'll need to run the headset, if you don't have one already.
Looking for a cheaper way into VR? Check out the Samsung Gear VR and the Google Daydream View. Powered by your smartphone, they offer a less impressive, but also less bank-account-destroying, VR experience for under $100, not including the requisite phone.
