To acquire the domain store.x.com, you need to follow several steps. First, check the availability of the domain through a domain registrar such as GoDaddy, Namecheap, or Google Domains. If the domain is already taken, it might be currently owned by someone else. You can perform a WHOIS lookup to find the contact information of the domain owner, or use a domain brokerage service to negotiate a purchase if the owner is willing to sell.

If the domain is available for registration, you can proceed by purchasing it through your chosen registrar. Ensure that you also check the registration terms, any associated fees, and renewals to maintain ownership. If the domain is crucial for your business, consider acquiring variations and related domain names to protect your brand.

In case the domain is not currently available but is essential for your business strategy, consider setting up domain monitoring with backorder services. These services alert you if the domain becomes available or they might automatically attempt to register the domain for you should it be released.

Lastly, when you successfully acquire the domain, ensure you secure it with proper DNS settings, and if needed, link it to your hosting provider to make your website live. Always renew your domain registration on time to avoid losing it to competitors.
