one of the domains that i want to register have expired on 25th June, but it's still not available to register, if i pay for the Godaddy backorder service, does it mean that i can buy it immediately?
If the previous registrar was godaddy and no other guys backorder the same domain through GD, the answer is Yes. Otherwise NO
unfortunately this domain was registered though "SCHLUND+PARTNER AG", i have never heard about this registrar.
Try to use Pool.com (need $60 to auth your account) SnapNames ($1 to auth) and GoDaddy (about $20) If you win, at GoDaddy you will not pay anything At Pool.com you'll pay $60, if u're only backorder domain, and it's going to auction, if there's more than one person who want't. The same at SnapNames, but price $59 for domain. SN and Pool has more "backorder power"
I wouldnt go via godaddy backorder service, I have used it a few times now and never once gotten the domain - they just dont do it fast enough.
