Google for it. I just did and found a couple of places that have it. Just make sure it is the Taylor K1515 FAS-DPD kit. A couple of links that showed up when I did my search were for other kits. The K1515A will have 0.75 oz bottles and the K1515C will have 2-oz. bottles.
I actually did find the K1515C on Amazon for $46. At the time I am writing this post, they show 4 available.Taylor K-1515-C- Drop Test, FAS-DPD Chlorine, (2 oz reagent bottles)I also found a Taylor K1515A for $21.63 from this place. (I don't know anything about this company.)
