Do the Math
To find the cheapest of something every time, check the price per ounce or serving. Bring a calculator to the store and take
the total price divided by the total ounces or servings. So if store-brand cheese is $2 for 8 ounces (25¢ per ounce) and name-brand
cheese has 4 eight-ounce packs on sale for $6 (19¢ per ounce), it’s a better deal to go with the name-brand cheese.
