Pennies are a dime a dozen (to coin a phrase). Without much effort, one could find a penny on the floor or in a parking lot. We may even pass one without picking it up. An article in the Atlanta Journal Constitution, however, relates the power of pennies when they join forces:

• A one cent per case increase of Coca-Cola would bring the company $45 million a year.
  
• A one cent-per-gallon increase in the price of jet fuel increases Delta Airline's company costs by $25 million a year.
  
• A one cent increase in the hourly wage for all the employees of Home Depot amounts to $6.5 million a year.
  
• If Krispy Kreme increased the cost of each donut by one penny, the company would increase profits by $27 million.
