Compare the unit prices of similar products to find the best buy. If the unit price is incorrect or missing, report it to the store manager. Ask the manager to post or correct the unit price information. If the problem is not resolved, contact your local weights and measures office for help. Look on page 21 for the answer.
Many stores use electronic scanners to figure the price at the check-out counter.
These scanners are linked to a computer that reads the price of the item. Some scanners are hand-held and the clerk runs the scanner over the price tag. Other scanners are on a counter and the items are passed over an electronic reading device. The scanner reads a code on the product or the tag and the computer computes the price. Many weights and measures officials inspect scanners to make sure you are charged the correct price.
