Taylor Reagents

You generally go through the R-0871-A FAS-DPD titrating reagent faster than anything else so you can get more of that, but be aware that it is also one of the more sensitive reagents so would normally not be kept for more than a year anyway. Most other reagents are good for 2 years and the acids and buffers don't degrade so will last many years. The organic dyes in the indicators are somewhat sensitive, but you can replace those after 2 years (though Taylor says to do this after 1 year). You might need more R-0870-I DPD powder as well. Since you will be testing pH regularly, you might go through R-0004-A pH indicator solution, but again this is something you don't want to keep too long anyway.

If you do a lot of CYA tests, then you'll go through a lot of R-0013-A CYA reagent.

Thanks!! (Good point about the stability/shelf life - hadn't thought about that!)
