Can SGAmmo notify me when a type of ammo that is currently out of stock returns to in-stock and is available for purchase?

Yes, provided the product is published in our online catalog but out of stock there is a button next the price marked ‘notify when back in stock’. Click that button, if you are logged in the system will put your email address on the notification list, if you are not logged in or do not have an account you will have to enter your email address once you click the button.  Once stock is added to the system an automated email is sent to your email address with a link to the product.
