Last Summer was the last time I was in a store(Fleet Farm) that sold powders, & they ranged from $19+/- to $27+/- IIRC. per pound or 14 oz., depending on mnfr..
As well, IIRC, primers were sold at around $4+/- .
The price of a pound of 2400 at a LGS there in Rochester,MN, was around $20+/- earlier last year. (2400 seems to have been hard to find last couple years, for me anyway, and I felt lucky to get some.)
I have since been buying in bulk online, since it is not that often I get to a place that sells such items & they are usually less expensive if I buy online when the hazmat is free or reduced. Otherwise, I could just drive & get the items for approx the same cost, if I were to buy in small quantities & by the pound/14 oz. at a couple pounds at a time. Bulk online , for me, is the better way to go right now.
I am well stocked now, as far as I can tell, based on my own shooting usage, so I am at a point to just buy as I need for my components as I use them up. If anything, it is primers that I will use up before the powders are gone, so they are the items to keep an eye on for me.
Costs always seem to rise & not fall, and "good deals" are not always available "when you want them to be", ( "Day late & dollar short"), so if the OP was asking the reason of deciding on whether to buy now,or not, my suggestion is to buy as much as you can afford when ya can until you reach the point you think you are set for a while. Then buy some more...
