To get your own custom domain name and email accounts for your Big Cartel shop you can purchase a Domain and Email Plan from the Aarcade theme shop. Aarcade’s Domain and Email Plan will work with a domain name you’ve already registered, or you can choose a new domain name to use for both your Big Cartel shop and your e-mail.

I have already registered a domain name

If you have already registered a domain name, you can manage your custom domain yourself or you can have Aarcade manage it for you. Refer to How do I set up a custom domain for my Big Cartel shop? for more information.
