Realistically speaking, prices can only go as high as folks are willing to pay, ergo if you refuse to buy ammo at $1 a round and others do the same, then prices will decrease, especially as the supply increases.
Personally, I refuse to pay the currently inflated prices on ammunition, but then again, I have more than enough ammo to get by until prices stabilize. At any rate, I would strongly suggest that ANYONE who is currently buying ammo do their due diligence by shopping around, establishing a baseline for the cost of ammunition, and refuse to do business with scalpers who are price-gouging (i.e. charging well over the going rate) regardless of availability.
Also, I urge people to remain calm, don't give into panic, and buy only what you need. There's no sense in spending in excess on ammunition and giving your money to crooks in the process when it could be better spent on food, water, medical supplies, and fuel. If you want to prep, then you need to learn to do it right by allocating funds towards more immediate necessities/essentials, and realistically speaking you're far more likely to run out of food long before you run out of ammunition. In fact, ammunition is in all likelihood the last thing that anybody is likely to run out of, including hunters, much less your average citizen.
Honestly, I cannot stress this enough, if you already have a decent supply of ammunition in stock, even if it's only a couple of boxes, then don't go spending $1 per round or more on ammunition, it's a waste of money and will only serve to drive up the cost of ammunition even further. I know that tensions are high right now, but if you allow the mere thought of danger to drive you into a a state of panic, then how can you expect to keep your head in the face of an actual threat? Be brave, be smart, and be wise. Remember that there is nothing to fear but fear itself, and that the greatest enemy a warrior can ever face is the fear within. If you can conquer your fear then you can overcome any obstacle, but crumble before it and you've already lost because you cower/flee before mere phantoms of your own imagination.
