Used to be able to get the 550 Federal 36 grain HP for about 15 bucks at Walmart before the shortage. GM also would have the 525 box at the same price after a MIR.

The best I have seen in the last year is Federal Auto Match 350 round box for 15$ and that was at BP during a black Friday sale. 2 box limit.

But I have to say, that automatch has been perfect in my S&W Victory and my Marlin model 60.

I have not seen the 525 or 550 bulk anywhere since the shortage. This includes Federal, Remington, and Winchester.
