Yes! Buying a custom domain with Magroove is pretty easy. Go to your My Websites tab on your Magroove For Artists account. Select the website to which you wish to buy a custom domain for. Go to the Domains tab and you'll see a field where you can search for available domains. Type the domain you wish to be yours and see if it's available! Once you choose the domain you want, click on Select and you can finish the transaction through Stripe or Credit Card.
Notice that the first option is a free custom domain we provide as soon as you sign up for a Magroove Website.
