Today they sent a email cancelation in a few hours. They noted the reason the orders were canceled was because they hadn’t been picked up in time even though the orders never made it to “processing”.
However, you can view the status in your order history. Once you see “shipping....” then you are good. Otherwise they can and will cancel anytime before that.
I ordered 5k of FGMM small pistol early last week. They sent me an email On Friday that it was delayed until 10/7 but they would keep the order for 60 days. They canceled it yesterday afternoon saying there was no inventory and then sold more of them last night. Of 10 orders of primers or highly demanded powder, I may get 2 ordered actually shipped to the store.
