Went ahead and called, got a fantastic and knowledgeable rep. She said that the offer is actually unlimited, and will last until they use up their quota OR 1 October whichever comes first. There are no charges and no restrictions, other than the mandatory 60 day transfer lock.*
She also said it is available to NEW customers also, so anyone having problems, have you tried multiple browsers? That seemed to help a few people.
Also, as long as the transfer is initiated during the special, then they are allowing a full 90 days for the transfer to complete, just in case someone updates their contact info and gets stuck with the Change of Registrant lock, this will allow plenty of time for the transfer.
My specific issue was that I forgot to turn off privacy and only did so after I started the transfer, so the approval emails are not getting through. She said if the system doesn't get a reply, it will REFRESH the contact email from whois after a couple days, so eventually they should come through. My other option was to cancel and start over, which I opted not to do.
*The standard hassles with NetSol are
1] you have to call to get Auth Codes, they try to talk you into staying. Best excuse say you sold the domain and they are pretty good about it.
2] push between accounts can be tedious - personally have not attempted
3] they will try and renew up to NINETY days ahead of time, and the renewal costs are high - $35ish
4] they have lots of internal marketing, there is a way to opt-out while you are checking out, not sure how to opt-out after the fact.
I am also fully aware that every rep has their own understanding so hopefully, the answers I got are accurate although some of this info does directly contradict what other members have been reporting
Good Luck everyone!
