KU prof says save money by using cash, not credit

LAWRENCE, Kan. (AP) -- A University of Kansas researcher says Black Friday shoppers who want to save a little money should use cash instead of credit cards when making purchases.

The Wichita Eagle (http://bit.ly/1bTuyGB ) reports assistant marketing professor Promothesh Chatterjee issued a statement Tuesday saying shoppers who use cash see their purchases much differently than those who use plastic.

Chatterjee says his research shows that marketers may be influencing how much people spend and what they buy by encouraging them to use credit cards.

He says people who use credit cards focus more on the benefits of a product, while those who pay with cash focus on its costs, including price, delivery time, warranty costs and installation fees.
