Ths site referrenced above did a study on the amount of chlorine loss under certain conditions. As you can see, it has a pretty good duration, but these bottles were also kept shut air tight.

Given that chlorine is the desired ingredient, at about 3% or less it becomes a low grade oxidizer unsuitable for contractor uses, but still somewhat usefull for the average homeowner who doesnt need the same concentrations as a contractor does. 12-15% chlorine stock should last anyone in the biz long enough to use it all. BTW...keep a lid on it

Caustic soda is added to give it a longer shelf life, check to see what you are getting before buying.

Just thought this would be helpful for others to know.
