I agree that the OP advertised it as "combine run". That may not mean much from some folks but I'm not a farmer and I interpreted that to mean that it was coming straight from the field if you wanted it. You can't blame a fellow for trying to sell something at a reduced price for a bargain. Some folks just need to understand what they're getting. If you want certified seed, be prepared to pay more because it costs more.
Lastly, the info may have come from aldeer but that doesn't mean it was a member. I think some of the forums, if not all, are open for public viewing. It very well could have been some competitors down the street who found it with a quick Google search and decided to report it. Either way, I hate it for you.
