Have a domain you know you will be keeping for a long time? Why renew it yearly when you could register it for an extended period of time and save money?
Many registrars offer discounts on long-term registrations. Usually the longer the period, the greater the discount. For instance, you might be able to get a 5% discount for two years, 10% for 5 years, and 15% for ten years.
By registering for an extended period, you can also ensure that you don’t forget to renew a name. I’ve done this more than a few times in the past with some of my more important domains and now generally renew them at least for two years at a time.
