I would like to get a domain for starting a blog. I am a bit confused on how the pricing works. When I signed up and was at the domain page, I chose one and it listed the pricing for it which is yearly. Do I continuously pay that price every year or is there a limit (a total amount of buying that domain)? Also, will this be the only thing that I pay for for creating a website? Sorry I'm on a low budget and want to know if there are any other fees to consider. Thanks!
