International Sales are not subject to GST (Goods and Services Tax)

By default all prices are displayed including GST. If you are an international customer prices will be displayed without GST when you are logged in.

If you haven't registered with the site, simply click the 'Register' button (top right) and follow the instructions. Once you are registered you can log in to the site at any time by clicking the 'Login' button.

GST equates to 9% of the price which appears on our site when you are not logged in as an international customer. (Therefore .. $29.95 = $27.25).
