I have two local stores I frequent. They are both pretty well back to normal, at least on powders that I use.
Between the two they had:
300 MP
H110
1680
AA#9, AA#7, and AA#5 I do not remember any AA#2.
HS6
Unique
Enforcer
BE86
BlueDot
Power Pistol
H322

I do not remember seeing any 2400. I do not use it, so I might have missed seeing it. I do not recall any WW 296 either.

They have finally been getting Red Dot shotgun powder again. No Promo so far.

One thing I have noticed is that prices have went up. Powders that were under $20 not that long ago are now $25 - $32 a pound.
The H322 for my 35 Bullberry Contender was one of the $32 powders at one shop, and $24 at the other one. I picked up the $24 can.
