An operator-unattended checkout system for processing articles selected for purchase and of first type bearing supplier-applied UPC indication and of second type not having supplier-applied UPC indication includes a reader for generating output signals indicative of article UPC indication where present on articles, a first processing part operable without customer input for using the reader output signals for determining first type article price and generating output signals indicative thereof, a customer-interactive display unit for use through customer input thereto for directing system operation selectively from such first processing part operation to the computation of second type article price, a scale for determining article weight and generating output signals indicative of determined article weight, and a second processing part operable on customer input to the display unit for using the scale output signals for generating ouput signals indicative of second type article price.
