UDPATE (11:32am): It appears that PSVR is available to pre-order once again — I personally just grabbed one.
PlayStation VR has sold out on Amazon UK — within ten minutes of the store page going live with stock information.
The page originally displayed an ‘in stock’ date of October 1, for the best part of a few minutes. Now, the page displays that the item is currently unavailable meaning that Amazon have already sold out of all their provisional stock. While the page may display that it will be in stock on October 1, attempting to add it to your basket will give you an error message, seen below.
