When you win a domain auction, the domain name should be pushed to your registrar account within a reasonable amount of time after paying. Based on some recent experience at NameJet, domain buyers should keep track of their NameJet auction wins to ensure the domain names are properly provisioned.
On April 23rd, I won a private auction at NameJet. I try my hardest to stay away from private auctions at NameJet and think I do a good job of avoiding them. I particularly liked this one and the price was right. On May 4th, I realized I had not yet received the domain name and submitted a support ticket to NameJet. NameJet support responded to me quickly, and by May 5th, the domain name was transferred to my Network Solutions account.
