I went looking for some deals on bleach today. Some stores did not list strength on their house brands. Its probably safe to assume its 3% bleach when not indicated on the label. At Lowe's 10% strength on one gallon size was $4.78. At Big Lots strength not listed(3%) 3 quart size $1.48. Dollar General was the only place I found 6% strength. The 142 oz. size which is 1 gallon-14 ounces was $2.00. Their 3 quart 6% strength size was $1.00. At Dollar Tree a real one gallon size strength not listed(3%?) was $1.00. In summary make sure of the size the container when comparing prices. In just the 4 stores I visited three different sizes were available 3qt(96oz), 1 gallon(128oz) and 142oz
