Then you’ve made the financial decsion to wait for the back orders. You’ve got yours, congrats. $30 isn’t much if you have no ammo or other chance to get some. The point is that there is ammo available, it is wildly overpriced, but it is available.
I think there is the case of price gouging then, as I can still buy today IN STOCK,
50 rounds of 9mm Sellier & Bellot for $14.95 and .22LR is always cheaper than 9mm except in the case of the 2 links you provided where some of the .22LR that wasn;t generic crap was double the price I posted for 9mm.
