Do you know you can only buy licenses that have never been transferred. Once they have been transferred once then they cannot be transferred again. Watch for that.
Are you interested in trading? I'm looking for transferable vbullitin license if you have one. Prefer vb5 or vb4.
If your still interested in buying a WHMCS licence I have one, it includes the Android APP access and 2 Token Authentication and is Owned and Unbranded. Has updates till 18th January 2014, and 2 Token Authentication is until March 18th, 2014. Im looking for around $300
