College book

I used this for early childhood and development class. This class is for either early childhood major or elementary transfer major. I am in the elementary transfer major, there are other people in my class that are in early childhood education. This book in my bookstore is $35.. I paid $29 with an on Amazon with their coupon. But I know it can be rented or bought used for around 20$(not sure about all used places that's at my school store). Life is hard I'm willing to let it go for a student cheap. 7$ alone. If you buy something else I will add it to your purchase for $4! I will just send the offer.
