I don't know if you can find someone who stocks it, or a distributor who carries it, but you can try:

Dave Anderson- I find the best place to find these Koolstop pads are old funky bike shops that have been around a while. Its crazy, but a few years back, I stumbled into a bike shop in the Twin Cities, (your neck of the woods?) and found stock piles of them. Regretfully, I only nabbed 4 pair for myself. However still using 2 pairs to this very day. Its my sense that they are still arund in quantity, just tucked away becuase "nobody wants them", as I recall the shop owner saying.
