a question... I got my Biology textbook from a friend, and now I don't need it anymore since I switched classes. could I sell it for the same price I bought it for, since I didn't use it?

it's also practically brand new, not highlighted or written in, and the pages aren't even bent

I plan to, I bought it from her for $100 and my parents say it's okay to ask that same price when I sell it

since I didn't use it, and it's barely used

I won't go below $75

but yeah it looks brand new, and it has the access code, untouched, for the online component with it

I will when I go in next, which might not be until school starts on the 31st

I have a couple other textbooks to sell too but I won't ask as much for them

they have a fb page but I don't think advertisements are allowed. I'll see if I can get there next week, I'll just have to hope that any people who want my books are procrastinating
