where to buy domain name

[alec11]

Where can we buy a cheap domain to be used for our personal blog?

you can find cheap domains by search at the google.you put the words "cheap domain" in it,you will soon find a lot of sites which offer cheap and good domains.

I wouldn't buy domain from unknown website if I were you.
Just stick with good site like godaddy and namecheap. It's to avoid being scammed
