I get my liquid chlorine gallons from a local farm & home supply store for $12 for 4 gallons, 12.5% labelled strength. Date codes seem to indicate it was manufactured about 2 months ago, so it should be at least 10% for a while. The manufacturer for the stuff I buy is in IL, Champion Products, and the store had PALLETS of LC just sitting there. However, since the pucks will be in short supply, I predict that LC supplies will be affected because of all the people who can't find pucks will start using LC.
