Best place I've seen for alkaline batteries is Costco. Kirkland
Signature AA are rated almost as good as Duracell and cost $.50 per.
Energizer Max and Gold are rated lower and cost more per Consumer

I bought a pack of Kirkland Signature AA batteries a couple of years ago
and started installing them in the 10 or so wall clocks in our office
when needed.

Now, when a clock stops and I go to replace the single AA battery in it
I find (every time) that the Kirkland AA has leaked chemicals out of one
or both ends, necessitating my having to clean off the contacts before I
put in a new (NOT Kirkland) battery.

I never ran into that kind of problem in recent decades with other
battery manufacturers' products. I suppose I could keep a schedule of
when I replaced a battery in a clock and put in a new one early enough
to prevent leaking, but I've got enough to deal with here already.

I wrote to Costco about this over a month ago and so far have received
nothing but an acknowledgement of receipt of that message.

Never again Kirkland batteries for me.

(You never get more than you pay for y'know.)

Reports.

I don't know who rated what, but I do know KGO (channel 7) News, in
San Francisco, did a battery throwdown, every Christmas, for years.
They put about 6-7 brand name batteries in a buncha those little toy
monkies that jump up and down and crash two cymbols together. IOW, a
motorized toy, which is a good test of batteries. Last toy running
wins. Energizers have won by several hours for years.

Another test, one I did inadvertently. I put brand new AA Duracells
in a mini-maglite in my van, one winter. It got down to about 25 deg
F and when I came out next morning at o'-dark-thirty and turned on my
maglite, zip! Nada! Not even a weak dull orange glow. Later that
day, I checked again and the flashlight came on full strength. Next
moring, another sub-freezing night, dead as a doornail! I changed to
Energizers and never had that cold weather problem ever again.

Now living in CO, so I don't see channel 7, anymore, but do know I'll
never waste money on a Copper-Flop, ever again.

The ratings were in the January Consumer Reports (page 7). I don't
usually get Duracells unless I need some right away. Can't recall any
issues. Someone once told me that Duracels were "oversized" so after you
use them you won't be able to use other batteries. I don't know if
that's true either. All sorts of rumors out there about battrees.

The Consumer Reports rated the Duracells #1 but suggests the Kirkland
Signature (#2) is the "best buy" coming in at 1/4 the price of
Energizers and Duracells.
