EDIT: sorry guys, offer seems to have expired. Per comments, you can use SUNTEN for £10 off.
HQhair.com is a valid GHD reseller according to the official GHD Web site:
http://www.ghdhair.com/customer-care/counterfeit
They're currently selling the GHD IV Style for £99, but there is a 15% discount code: <b>15HQHAIR</b>.
International shipping is £8.50 for the first item, £12.50 for an unlimited number of items
Also, buying overseas means that you will not have to pay the 17.5% VAT, but you do have to pay a £8.50 "service charge" (EDIT: per the comments, this gets removed if you pay via Paypal - thanks guys!)
Anyway, all up, one GHD IV will cost you £88.62, which at the current exchange rate (x-rates.com) is <b>$141.57</b> (excluding any credit card surcharges, foreign exchange surcharges, etc. that your credit card provider or Paypal will charge you).
Or, if paying by Paypal - £80.12 (~AU$127.99)
Also £99 at asos.com but there is no discount code at the moment.
