When the expiration date of a domain name has passed and after the end of a period of time during which it is renewed at its normal price, then it goes into a redemption period. If you want to renew a domain name that is in the redemption period, you will have to pay an extra amount of money plus the 'normal' renewal amount. The dates and times mentioned above vary, depending on the tld. For example, when a .com domain name expires, for 35 days it is renewed at the normal renewal price. If these 35 days pass then it enters a redemption period for the next 40 days. To get out of the redemption period, you will have to pay 160 euros plus the renewal cost.
