I get 91% for cheap at either target or WalMart and it owrks for most
general purpose applications. No good for things like video heads and
other sensitive applications though.
I used to always get 99% at the local Snyders Drug store for still a
reasonable price (few bucks for a pint). I haven't checked recently
(still have quite a lot on hand) but I think they still sell it. If
it's not on the shelf, ask at the pharmacy counter. I'm sure they can
order it and Snyders has always been easy to work with.
