Used 2007 Book on Import/Export market of Audio parts for $7

In addition to headphone-related stuff, I occasionally post random “deep cut” type of audio-related products. This is one of those “occasionally” times. Amazon Warehouse Deals (AWD) has a used copy of the book with the railroad title of “The 2007 Import and Export Market for Parts for Audio-Frequency Electric Amplifiers, Microphones, Loudspeakers, Headphones, Earphones, and Combined Microphone-Speaker Sets in United States” for $7 and it is Prime eligible, so if you are a Prime member, shipping is free as usual as AWD actual is the seller
