Hey, I didn't write the post, but looking through the comments, he says he did get some sites from flippa. But mainly he did a "rediculous" amount of work. Seems like that means he was spending all of his time looking for ecommerce sites anywhere he could think of – flippa most likely included. So it's just a numbers game, he's plowing through lots of opportunities, finding some on flippa, finding some on other places... lots of hustling.
