Asda have the remote control electrical socket sets back in stock. You get 3 in each pack and they are made by Status. They are advertised at £5.00 in Stockport store but this is Nationwide. Now the good news is that at the till they come up at original price £15.00, so pay this then go to customer service with your receipt. They will give you the £10.00 difference back and a £2.00 gift card. So overall only cost you £3.00 - mega bargain !
