How would you like to save on domain registration? Yes you can to that by applying discount codes. Most registrating serices provides a place where you can apply the discount codes. Using it is not the problem but finding of the current and valid discount code is.
I am using namecheap.com for my domain name registration and to find the current discount codes I head over to http://www.hostingdiary.com/2006/08/namecheap_disco.html. There the site provides the latest discount codes for the current month. Like wise you can use Google to search for discount codes too.
