Out of curiosity, what domain registar do you use? With GoDaddy, I pay $14.99/yearly for .COM Domain Renewal and $9.99/yearly for Private Domain Registration Renewal. It seems a bit price-y but I'm completely unaware of other competitor's prices.
I use Namecheap, but it's not the cheapest. A couple months ago on a thread here in HN a bunch of people were recommending Porkbun, which seems quite cheap (~$9/year with free private domain), but I've never used them.
