John Marshall Harlan II,
Idaho Sheet Metal Works, Inc. v…
“ Within the category of goods and services that can be sold at retail, naturally not every sale can be so classified. The exemption itself excludes any sale for resale and beyond that, references in the legislative history, n. 14, supra, and common parlance certainly suggest that the term retail becomes less apt as the quantity and the price discount increase in a particular transaction. Again, we do not believe the word usage of the industry must be given conclusive force. ”
