Seller picks who gets the goods. No rules as to 1st come. No way we could track that.I always thought the "PM sent" was more of a queue ... If you saw 3 "PM sent" ... you could join the line - knowing your chances were not good
I do not remember seeing any complaints where the 4th guy in line got it over the 1st guy in line - (by offering more $$$ )
I have been ignored because I am staff and have given warnings so the adult meat suit with the childs mentality ignored my full cash offer more than once.
Again....seller picks the winner.
