At any random time and at any random store, there are going to be supplies on the shelves which then get posted on these type of forums thus creating the illusion the shortages are ending. These supplies typically last a very short time (hours) and are far and few between. Wish I wrong but I see no end in site.
I just picked up a 525ct Remington "Value Pack" for ~$21, but nothing is regularly available. I wasn't entirely pleased with the price as compared to 100-ct boxes for ~$1 from years back. I'm not sure if it's merely a function of inflation or supply/demand law at work.
In any event, it seems we're going from ammo shipment to ammo shipment - similar to living paycheck to paycheck - not a good situation at all.
