There's no need to pay full price for domain names these days - Godaddy usually runs promotions every day of the week.
The saavy business person will do a search on Google - something like this: promo codes godaddy
For over the last 5-years I've been buying & renewing my domains at a discount by using the technique above, as a matter-of-fact - I just purchased a new domain for 2 years at a price of $6.89 each year as opposed to 10.69 per year.
The link below is one I go to often:
You enter the coupon code at Godaddy prior to checkout.
There shouldn't be any reason why a business owner DOESN'T have their own domain name, especially for only $6.89 a year.
If you're using a free blogging service like Wordpress, Blogger or some other you can purchase a branded domain name at Godaddy and redirect it to your blog or website.
Now get out there and do it!
Press On To Success,
