I'm using Gunbot. When the reseller notifies Gunbot they have something in stock, Gunbot posts it with how many minutes ago it was posted. Once it sells out, they add SOLD OUT to the entry for that powder. Two days ago, I saw AA#7 and Power Pistol (twice) post and sell out in under four minutes. Those two stand out because I'm looking to buy them, but I've been seeing all sorts of popular powders pop up regularly lately. They don't last long, but they're at least hitting the shelves instead of just filling backorders. I'm just posting here to give people a little hope. I'm seeing a lot more of the popular ones than I was a month or two ago. ;-)
