As soon as I mentioned escrow to ash312 the user responded:
[3:47:26 AM] goldux officials: i found an other buyer
[3:47:33 AM] goldux officials: will tell you if i need
[3:47:39 AM] goldux officials: yes i use escrow
Also, when I asked the user to send me his/her skype username in a Private Message on Bitcointalk. The user initially sent me the wrong skype.
