I would also like to add that people who post about availability of components on public forums is one of the worst things they could do. I know they may not be smart enough or experienced enough to understand why and think they are just helping, but they are only making things worse. It's not a good service, but actually a complete "disservice" to everyone as a whole.
If a person really needs a certain component, they will put in the due diligence day in and day out until they find it somewhere. Whether or not they find it at a fair price is a different story of course. But when a person posts availability of components in a classified ad like this, every hoarder and shark looking to buy and resell to price gouge sees the same thing. And the people who are price gouging with a lot of money at their disposal won't hesitate a second to go and buy up every bit they can to resell at high prices. These ads might help a couple honest people out, but they do not help anyone at all in the long run when the hoarders and gougers are getting the same heads up.
Even at those high prices for BR4 primers shown at midway, a price gouger will still buy them and resell for an extra $50-$100 profit. So think about that before you go posting about where to find components when there's hoarding and price gouging going on.
