My SOP is to only pay what I consider to be a (better-than-)decent price for a product.
My ideas of decent pricing are
not affected by any prevailing winds of Crazy (e.g., currently I will not pay more ~28¢/rd for good-quality M193-equivalent ... delivered).
After the Panic has calmed and pricing has flattened I will modify my personal pricing guidelines.
If I run out of 5.56x45 while the market price in the stratosphere, I will simply stop shooting my ARs for awhile. <shrug>
So ... if I happen to stumble across a decent, or better, price for a product that I use I will consider making a purchase.
The way that the current Silliness is developing, it may be awhile before I make another firearms-related purchase.
For me that is OK since I have the PackRat Gene and have stockpiled a whole lot of, among other things, firearms, ammunition, hand-/re-loading components, parts, accessories, etc.
