Complications have hampered the adoption of Universal Product Codes (UPCs) for fresh produce until recently. The data being collected using Bar Codes and Price Look-Up Codes (PLUs) have many applications. A case study of carrots demonstrates how analyses of scanning data can show the effects of new items on established products and the customer's willingness to pay for the new products.
