Short on pennies, Casey's to round cash sales down to nearest nickel

Casey's is the latest store to feel the pinch on pennies after the U.S. Treasury stopped minting the coins.

Ankeny-based Casey's General Stores follows the lead of La Crosse, Wisconsin-based convenience store chain Kwik Trip — known as Kwik Star in most of Iowa — which announced in October that it would round cash transactions down to the nearest nickel when customers do not have exact change.
