the local home depot has 10% bleach for $1.99/gallon and 5.25% bleach for $1.30/gallon and my local pinch a penny/leslies pool supply sells 10.5% 2.5gallon yellow jugs for $4 a jug which equals $1.60/gallons for 10% seems to be the best deal around, i will definitely now go look @ wal mart and the local dollar stores to try to find a cheaper way to go but for now im stuck @ the local pool stores which i hate!! owell
