Hey, so I bought a Physics 70 textbook on Amazon for 82 dollars, but I don't need it anymore. To save myself the hassle of shipping, I'm willing to sell it for 75 dollars. It's used, but in good condition and structurally sound. The bookstore sells used copies for $121.50, so this is a great deal. I'd prefer to sell it as soon as possible so I can return it if no one wants it. Let me know!
