I don't know whether others are also getting this error. Every time I initiated a transfer of domain to Godaddy and clicked "proceed to checkout" I would get the following error message: Your domain names are already in your cart or your session has expired following 20 minutes of inactivity. Please check your "Cart" or click on "Domains" above to restart the purchase process. I restart the process over and over again and the same problem occurs. What's wrong with Godaddy?
it say,.. your cookiee may deleted , log in again to complete purchase of your domain.. another clue is,.. you may take a long time when purchase the domain..
I think I also experienced that too using Firefox, I just clear my browsing history then try again and it works..
just happening to me right now ... i use proxy to access godaddy then show that message. if i not use proxy that message not shown.
