Today, Oculus announced a limited supply of the Oculus Rift would be available from Best Buy starting May 7.
Orders will be available online from Amazon, and Microsoft stores starting May 6th at 9 AM PST.
Best Buy will also offer in-store demos of the Oculus Rift on May 7th as part of the Intel Experience. Initially, this will be in 48 stores and expand later.
In an interesting twist. Oculus will allow those who pre-ordered their Rift to purchase at retail and cancel their pre-orders but STILL maintain their place in line for Oculus Touch controllers other pre-order benefits:
We know that many pre-order customers are still waiting for their Rifts, so we're offering those customers a chance to purchase Rift from retail instead – while keeping their pre-order benefits, like the EVE: Valkyrie Founder’s Pack and priority status for Touch pre-orders. Starting May 6th, if you’re interested, simply go to your order status and let us know you’ve purchased a Rift at retail, and we’ll cancel your pre-order. Your EVE: Valkyrie entitlement will appear in your order history.
If you don't want to wait in line at Best Buy to try the Rift. You can set up a demo via their Oculus Live site.
