I post and I get between 0-3 responses every time.
I make it clear in my post that I am a collector, not a dealer, and I really enjoy fixing them up.
I have met some really neat people in the process, and had some cool experiences. Even got to go up to Marco to pick up a junk cabinet there and got to tour their place.
I'm sure I seemed like a goober, being all wide-eyed at the NIB pins, as well as all of the older pins they had there.
I do get responses from flippers that try to sell me a game at a ridiculous price, but I just thank them for the response and politely decline. You never know when they will drop the price and contact you again, or have something else for sale.
