If you have a Harbor Freight nearby, try getting some NiMH AAAs.
Might also be available at Fry's, Target, Wal-Mart. You in Canada?
I'm not a fan of alkalines, either.

Look behind that package -- I'll bet there's another one on the peg. :-)

Yup, Canada. I'm still liking my original idea of using larger sizes
in smaller slots rather than using geniune AAA batteries; perhaps
because they last longer, or perhaps because I like playing God. (Cue
lightning, evil music and laughter, and shadowy scenes of me forcing D
batteries into AAA slots)

HARDY HAR HAR, FUNNY.
:P I meant per package. Though even if I could find them in larger
quantities, I still like the major life advantage of the larger sizes.

Yup.
Check out:
http://www.batterybob.com/category.asp?cat=9002
Notice that in quantities of 500 the AAA's are still 3 cents more
expensive, each, than the AA's.
Also, the AA's have a capacity of around 2450mAH, while the AAA's
can only put out 1120mAH, so the cost per ampere-hour for the AA's
is:
$0.19 $0.0775
nAA = -------- = ---------
2.45AH AH
While for the AAA's it's
$0.22 $0.196
nAAA = -------- = ---------
1.12AH AH
So the cost for the AAA's, per ampere-hour, is about 2.5 times the
cost of AA's, and (neglecting the differences in the spec's for the
rate of discharge between the two) they only last about half as
long.

Reminds me of powdered sugar (I needed some for a fudge recipe).
Powdered sugar costs about double the cost, per unit mass, of regular
granulated sugar.
If you make powdered sugar yourself by putting granulated sugar in a
coffee grinder, you will find that 1/4 cup of granulated sugar makes
1/2 cup of powdered sugar.
So you're paying double the price for half of something that you could
make yourself.
