Actually I was THIS close to posting just such a thread of my own a week and a half ago. The night I was going to, he asked for only one more day, and the next day I had a tracking number, a day or two beyond that a money order for quite a sum of money.
I did some research before thinking of posting last week and saw that apparently he normally pays people however much money reasonably quickly and all that, nobody else seemed to complain, but when it came my turn I was getting some special treatment, which didn't make sense to me. Some people have reasons for this type of behaviour, some don't, and some have them but won't share regardless, so while it can be annoying all I can recommend is that you show only as much patience as you feel like. In my case, everything worked out in the end. Best of luck to all of you.
