Use a Custom Domain to forward to Castiron Shop
Almost all domain services allow you to forward (or redirect) all traffic to a custom domain to another site.
By doing so, someone can attempt to visit a url like kulturedkombucha.com and when they click or type the link, they are actually re-routed to the url of your choice. Castiron has plans to allow for fully custom domains in the near future.
