Welcome to WebmasterWorld Guest from 22.214.171.124
A domain of mine expired a couple of weeks ago and it is on the redemption period. My registrant want $70 for renewing it in this redemption period - and I've heard that this price is not abusive, but I am not eager to pay it. The domain is personally valuable but nothing especial, not much traffic.
I am not interested in any service that helps me buy expired domains. If I can grab my domain back by my own is fine, if not it is not the end of the world.
Is there a way to calculate the exact second?
Not really -- not anymore. It all depends on the particular registrar -- how long they hold the domain name, before putting it into real "Redemption Period" (if they do at all) -- and if they have a partner-relationship with one of the secondary-market auction sites.
You could try and ask your registrar, (1) if they have a relationship with an auction site for their "expired domains", and (2) if not, how long do they hold the domain ("Registrar Hold") before they release it to "Redemption Period". As the saying goes ... "there's no harm in asking".
You could also take a look at this thread [webmasterworld.com] in this forum, that may give you a little more info.
