Hard to find these days. Used to be much more available, both in the 12 oz
aerosol cans, and the boxes of 3 4 oz. plastic squeeze bottles.

I used to buy the aerosol cans at Walmart, but now they have discontinued
it. I don't see it in any stores. The only places I could find online were
like $9 a can! (Walmart last had it at $2.34 per can).

Well, I finally found a new source (from someone's blog online), so I guess
I should share it here, as others are probably searching for the stuff.

Call 1-800-Blairex (1-800-252-4739) to buy the 12 oz cans directly from the
manufacturer. The price is $2.82 per can, minimum order of six. If your
order is over $50, then shipping is free.

(Interesting. It's that Blairex brand that sells retail online for something
like $9 a can!)

Besides using it in cleaning contacts, I use it directly in my eyes to wash
them out, both with and without contacts on. I also sometimes use it to wash
out my nose and sinuses. So, I'm glad I found another source.

I have seen the boxes of 3 4 oz. plastic bottles of non-preserved saline at
Long's drugstore (their own brand) lately for $5.99 per box (also 12 oz.)

The closest thing otherwise is Ciba Softwear Saline. It is preserved, but a
different way than other preserved saline. It feels to the eye like
non-preserved. I found a source for that online for $2.99 per 12 oz bottle,
much cheaper than through other retailers. I forget the URL though. I can
look it up. (It was found on Froogle (Google shopping), so you can probably
find that source as well.
