If you see a caliber you shoot on sale, pick up two boxes (more if you can afford it) then you can shoot one and save one or more. You'll have a nice supply in no time.
If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen. ― Samuel Adams
