How do I add a Thank You page to my Wix Online Store?
You can redirect your customers to a Thank You Page after they completed a purchase in your Online Store.
To add a Thank You Page: Click your Shopping Cart to select it > from the pop-up menu, click Settings > click Add a Thank You Page.
A new page will be added to your Site. You can edit the page just as you would any other page on your site. Clients will be directed to this page after they complete their purchase.
