Step 1:
Go to domains.yahoo.com.

Step 2:
Type in your desired domain name and press the "Search" button to see if it is available. If your first choice is taken, you will have to repeat this process until you find a name that is available.

Step 3:
Press the "Sign Up" button, which will appear once you have chosen an available domain name.

Step 4:
Choose whether you want to purchase the domain name for one, two, three or five years. Press the "Continue" button.

 

Step 5:
Verify your Yahoo ID by typing in your password. This is required for verification purposes before proceeding. If you don't have a Yahoo ID, then you will need to create one before you can proceed with your purchase.

Step 6:
Input your credit card information into the supplied form. Once you have double checked that all of the information is correct, press the "Continue" button.

Step 7:
Review and confirm your order. Make sure that all your billing information is correct and that you have selected the package that you want. This is important because, once you proceed, you will not be able to make any more changes to your order. Once you press the "Continue" button, you will be the proud owner of a new domain name.
