No, sometimes it DOES work out that way. Say it's actually 10.5% vs 5.25--then if the LC was less than double the price of the 5.25% bleach, it's cheaper.

Suppose that 5.25% is $2/gallon. A carboy of 5 gallons of 10.5% is the equivalent of 10 gallons--therefore ANYTHING less than $20 for the carboy is a bargain...given those numbers.

I find the carboys convenient (I recycle bleach bottles to refill) but I'm aware that at 12.5-14% the chlorine breaks down fast. I'll fill empty bleach bottles with half-water then half LC to get it down to the 6-7% range...Lately it's STILL cheaper than bleach.
