We don't ship ammunition automatically. You have to request your ammo (or confirm you are ready for a shipment if you get an email notification).
In short, we are not a traditional e-commerce site where you order something and it ships immediately. Our service is built around ammo accumulation over time in your own ammo "piggy bank". We no longer ship out automatically, but we have automated email notification triggers you can set for certain thresholds around round count, time, or dollar value.
