A. If you register on the AquviiCLUB registration page on our homepage (scroll down at the bottom of this page), you will immediately receive a confirmation email. You will be redirected to a page where the free shipping coupon code is displayed, so if you enter the code when purchasing at the Aquvii Online Store, you can use it immediately. It may take some time the first time, but from the following month, we will send you the coupon code in our NEWS LETTER several times a month, so you will be able to use it more smoothly.
