Reddit mentions of Mechanics And Thermodynamics Of Propulsion

Sorry that other people are being harsh critics, but yeah man. Respectfully, a couple of these are pretty overpriced.

Thing is, most people would rather buy a new book from the store than buy a used book for barely less than retail. I suggest you lower the prices, especially keeping this in mind:

Astrodynamics sells new for $17: https://www.amazon.com/Fundamentals-Astrodynamics-Dover-Aeronautical-Engineering/dp/0486600610

Propulsion sells new for $25: https://www.amazon.com/Mechanics-Thermodynamics-Propulsion-Philip-Peterson/dp/8131729516/ref=sr_1_2?s=books&ie=UTF8&qid=1526807320&sr=1-2&keywords=mechanics+and+thermodynamics+of+propulsion+2nd+edition

Your edition of COE 3001 sells new for $113: https://www.amazon.com/Mechanics-Materials-James-M-Gere/dp/1111577730/ref=sr_1_2?s=books&ie=UTF8&qid=1526807508&sr=1-2&keywords=mechanics+of+materials+goodno and it's also not the current edition

Best of luck. And if you find someone looking specifically for the current edition of the Mechanics of Materials book, please send them my way!
