Buying household basics one package at a time may feel easier on the budget, but that convenience can quietly raise what you pay per use. For products your family goes through predictably, larger packages and multipacks can reduce the unit price and the number of emergency store runs.
Consumer Reports has found meaningful price differences among retailers when comparing household products by unit cost rather than sticker price. The key to buying household items in bulk is stocking products you will actually use, not simply buying more because a package looks economical.
