Principles of Real Estate College Textbook (Gently Used)

I have a number of college textbooks from when I went to school for marketing and real estate. I purchased at school for $100- However, I see that amazon sells used for $40. So, I will let it go for $35 with free shipping if within USA as it would ship fast. If outside of USA then I prefer to sell it for $50. If you’re low income still send an offer as I think everyone deserves to get education (money shouldn’t be a barrier!) I do also have some other books from different classes: Marketing, Math books, Spanish, etc. so do let me know if I should post the others. Thanks!
