It's worth checking the yellow pages and asking around about industrial suppliers as well. I had seen a sign in my end of town for a while saying they sold chlorine, but was content to slug Walmart bleach. I finally dropped in and found they sell 12.5% at $6 CDN for 10 litres (about US$5.30). At PPM that's about 1/3 cheaper than Walmart's bleach. They guarantee 12% and I believe he said it's 12.8% when delivered. Needless to say, they go through a ton of it and its pretty fresh.
