Store
What you're checking
Shelf price, package size, and the unit price as printed — usually cents, like 15.5¢.
Decimals are fine. Most shelf tags print this in cents, like 15.5¢ or 40.0¢.
This checks the arithmetic you enter. It is not a finding that a store meant to overcharge. Rounding, a sale, or a bad photo can open a gap. Nothing here is pulled from a chain price list.
