If it's still pending renewal you can't backorder it yet. If it's at GoDaddy then it has a cycle to go through, where it will hit GoDaddy auctions before it ever gets the PendingDelete stage. If they haven't renewed then give it 30-40 days and start browsing the GoDaddy Closeouts at auctions.GoDaddy.com - Once it's in the closeouts you can buy it and it will be yours assuming the previous owner doesn't renew it within that week that it's in the Closeout auctions. This will cost you at most, $25 or so
