Based on our laws we are required to collect tax on goods and services.
Sales tax is determined between Clickbank and the location you are purchasing from. It is 100% out of our control, it isn't a setting or an option we have.
Part of the Clickbank system, is they handle all the credit card processing, earnings disbursement, etc. between affiliates, vendors, and the government.
We apologize once more, unfortunately, this is out of our control.
