Why it matters
An expired domain is not always gone. During the grace period the owner can usually renew at the normal price. Some registrars list the expired name for auction before the period ends. After it comes the Redemption Grace Period, which costs more. For sellers, never let a listed domain expire. For buyers, an expiring name is not yet available. A common mistake is assuming the domain drops the day it expires.
