I don't understand why a new thread is a good thing--especially since it's something that only invited members can access. I think that "leeching" is used in the sense of lurkers stealing thrifting techniques or spots? And the answer's to create a thread for the full-time or hardcore flippers--despite the fact that I can't remember ever seeing anyone share locations (occasionally someone might have admitted to getting friendly with a sorter to get into the back room).
This thread's created and fostered the community of hobbyists that some posters might be trying to turn into a community of career thrifters. There should probably be a forum for guys who do this for a living, but how many of those guys live on this thread?
Three stores recently started letting me do this on a regular basis. All three privately owned, and the owner was the one who offered. They all three, thank me repeatedly, acting like I am doing them a favor by buying some of the stuff out of the back to clear up space.
