Kodak still sells Glacial Acetic Acid. It comes in 1 gallon plastic bottles for about $30. I have forgotten the price, but that is close to what I paid about 2 years ago. One gallon of acetic acid is a lifetime supply for one of us, I would imagine.
I simply went into my local photo store and tried to buy some, and he said "Gee, Kodak doesn't sell those little bottles any more, let me look it up", so he got out his Kodak catalog (yes, there is still a printed catalog and he gave me one) and yes, there it was, Cat # 64-19-7.
