We’ve got confirmation now (from friend of the site, Vooks) that whilst JB Hi-Fi is not honouring the specific order, they have sent each person who purchased the deal a coupon for $14.70. This effectively makes the product the same price ($34.27) if they re-order it before the 16th of June (when it goes off sale).
The email reads:
We are sorry for the delay in the processing of your order.
Unfortunately, there has been a pricing issue in our system that has prevented your order from being completed. The 12 month PS4 subscription was incorrectly advertised at $34.27 and so as a result all orders have been automatically rejected.
As a gesture of goodwill, we will be emailing you a gift card to the value of $14.70 which can be used to place an new order for the subscription at the price of $34.27. If you wish to do so. Please note that this subscription is only on sale until 16/06/2017 so if you would like to purchase this item at the same price, it will need to be done before this date.
