Are any parents here interested in selling the used books? - Page 1

I have 4 year old kid who loves to read the pepper series ,curiose george series,finding nemo ,bala hanuman etc..etc....when ever we go out  he insist us to buy the new book.We are quite happy that he loves books more rather than toys. Now i am thinking that instead buying the brand new book,if i buy the used book i can buy more books for him.

Are any parents here interested in selling the used books? Books should meant for  4 to 6 year old .

Thanks in advance!!!
