Without a doubt there will be many items totally unavailable. Take a common caliber, the 6.5mm Creedmore. Two (plus) years ago,. single quantity box of MATCH GRADE ran around 15-16 dollars. Then, no matter which of the special ammo search engines .... NOTHING for over a year ..... nada ....taja!
Then, it started becoming available at $3.50 a round (70 bucks a box).
Many of what used to be readily available rounds are totally gone ... can't find 'em anywhere.
That is ammunition. Next will be fuel, followed by food.
Granny be sendin' Jethro down to the root cellar to take inventory (that boy can cipher up a storm).
