Expiring Domains are domains which are already registered with Joker.com, but which have not been renewed by the former owner. You may purchase them right before they are deleted - once they are deleted, they may be gone for ever.
Expiring domains are not 'weighted' by value, we offer them all for the same price, which is mostly set by the registries.
The price consists of the regular RGP fee, plus the price for a regular renewal for one year.
That's why you really may make a snatch here.
Please note: The Joker.com 'Redemption Grace Period" procedure is currently used to move these domains into your portfolio.
