I used Yahoo Small Business, DirectNic, eNom, GoDaddy, you name it I used it. I got tired of them raising the rates on me as soon as I moved all of my domains from one registrar to another.
Consequently, I became a GoDaddy reseller so I could give myself the rock bottom prices GoDaddy allows me to set it at. Right now it's $7.99 and that not only for registering but also renewing.
Low priced domains will get you to register you new domain names then jack the renewal prices up. I have the same price for new registrations and renewals. I'm not in it to make a profit but just enough to cover the annual reseller costs.
This is ideal for people who have large domain portfolios like me. So if you have a large domain portfolio, check out my GoDaddy reseller account and know that it's the lowest price GoDaddy allows me to set it to.
