How to change/modify billing address?
The billing address will be automatically generated to the same as the shipping address. If you want to change it, you can click on "Edit" at the check out page (after clicking the PLACE ORDER button). Please find an example below.
If you paid already, then no need to change the billing address, as we'll just ship the order to the shipping address that you left on our site.
Therefore, it does not matter that the billing address is different from the shipping address.
