Just bought myself a pair of ugg boots from USC, noticed them on there before and was just waiting for them to come back in stock in my size. RRP£170 but with the 20% off voucher it comes to £136, £4.50 delivery by UPS but I didnt get charged for delivery on checkout. They have just got the cardi UGGS back in stock too which with the voucher you can get for £88!. Get them ASAP as they have announced that 13 of their shops are going into administration (not the whole company though) you have a guarantee anyway so if they do go down in the next few days (unlikely) you still get your boots.
Hope this is helpful!
