Check Your Receipts Have you ever helped with the

shopping? Groceries are a big expense for most

families. Some people use a calculator when they

shop. As they pick each item, they punch in the

price. They may know their total even before they

reach the checkout.

Some people watch as each item is added to the

total. A mistake of one decimal place can make a

big difference. For example, a $0.59 item could be

read as $5.90. How much would a mistake like this

cost?

Computer checkouts have helped to prevent some

mistakes. However, some people still check their

receipts very carefully. The next time your family

brings home a grocery receipt, check the total with

a calculator. You should also read each item to

check for other mistakes. What other mistakes

might be found on a grocery receipt?
