We try our best with the links to redirect people to the best Amazon store based on their location. For the 2 link examples, you have provided the first one goes to Amazon Australian store and the second one goes to the U.S store. The best approach might be for you to go to the correct Amazon store first and do a search for the product. I do hear that Amazon Australia has just opened and that some of the prices are quite high…. I am not sure what is best for your location?
A replacement as loved the first ghd straightener I bought.
