Each website has 2 components.
1. The Domain: Web address for the website
2. Web Hosting: Where the site lives and data is stored
If you are launching an InflatableOffice website we provide the web hosting for free within the WordPress Plugin on your plan. You don't want us to own your domain though, that is something that should always be registered to you only.
There are many places to purchase a domain name, you can Google "domain registrars" or we purchase our domain names from NameCheap.com. On any of these sites you will enter the web address you wish to purchase and they will show you the annual cost, they are usually anywhere from $7-15/year (USD).
When purchasing your domain you don't need to add on any hosting or security packages since we provide all of that will set it up on our end for you!
