Yeah, I couldn't find it at Costco last week, and I thought, well, that's weird, and then I saw this thread and figure that's why. I still have about 3/4 of a large bottle left, I'm just going to have to be extra careful not to splosh any over the sides as I fill the cup!

The article I found online said that stock should be in by April, well, hmm, haven't seen it yet.
If you look at the bottle of aosept it says hydrogen peroxide 3%, sodium chloride (salt), and potassium sorbate (preservative). That's it! If you look at the generic hydrogen peroxide the bottle says, 3% hydrogen peroxide.
Ya gotta wonder what we're paying the other 8 dollars for. I will say that I had to rinse the lenses really well (I use optifree to rinse only) because the lenses felt a little odd, like I had gotten water in my eyes from the shower-I'm guessing it was because of the lack of salt. It wasn't *great* to use the generic, but it didn't bother my eyes, either.
