It's always been done from his home. But when he was competing he had someone else doing the job. That guy would probably still be doing it if he didn't screw up.
Sometimes when he goes away for a couple of weeks or more, his girlfriend will handle it. Other times the orders will stack up and he will get a few of his friends, like myself, to go over and help.
Here's the coolest thing for fans. If he's out of stock on something that's ordered, he'll call you personally to see if you want to sub something else in or wait.
People always are shocked to hear from him. Only problem is he won't just hang up and sometimes the conversation goes on for a while.
