GHD IV stylers, had a quick search and it seems like a good price to me. Voucher says it can't be used with electricals but it worked for me. Use code 15HQHAIR to get this price thanks to jonnydixon1990 for the code.
They also have the mini stylers at this price and the wide plate work out at £8.50 more.
