Why are the ghds much cheaper than the official site's?

Because we are one of agent factories who are producing ghds for GHD official company. Now, in order to celebrate our anniversary and express thanks, our factory will produce more than the quantity which GHD official company requests. For example, if they order 5000 sets ghds, we will produce 5500 sets, then this website sell the rest 500 sets at cheap price. However, make sure that the 500 sets are the same as those 5000 sets.
