When I was running my gun department during the peak of the last big ammo shortage, I would literally buy all the ammo I could get, and put it out to sell, usually with purchase limits. Frequently, I chanced upon large bulk packages, particularly of 5.56 or 9mm ammo. It would have been easy enough to resell a 1000 round case of either, but that would have been helping just one customer. So I repackaged, using ziplock bags and labeling them with exactly what was in them. That way, a 1000 round case becomes 20 50-rd. bags. With a 2 bag limit, that allowed me to say "yes" to at least 10 customers frantically looking for ammo.
