I've started noticing some sneaky math in my local supermarket. When comparing two items, both list the unit price, but they list the price in different units. Example: A 1.4-lb package lists the price per oz, while the 0.8-lb package lists the price per lb. In every case, the intent seems too be an attempt to induce math errors and cause someone to accidentally purchase the package with the higher true unit price.
