I bought two bottles about 20 years ago, and still have a dab left! It lasts forever! Another tip, and one I recommend if you want anything near archival permanence, is to use the two solution fixing method. When you start a session of developing or printing, use one solution for the recommended time, and a second solution for half the recommended time. When the first solution tests as exhausted, discard it, and you make the second solution your first solution. Make a fresh batch of fixer for the second solution. This method of fixing, and proper washing will assure you of prints that will not develop a nasty yellow stain many years from now! Cheers, Dan'l
