Have seen a number of requests for deals on these. Seems a great price for 2 microphones to be delivered free with super saver delivery.
It does state that they are out of stock but will ship item as soon as it is in stock.
Quote from site: "Temporarily out of stock.
Order now and we'll deliver when available. We'll e-mail you with an estimated delivery date as soon as we have more information. Your account will only be charged when we ship the item.
Dispatched from and sold by Amazon.co.uk."
