Post PMR Spring clean

When Adik finished her UPSR, I did the spring clean for all primary school books.  Now its time for spring clean again but this time is for form 1-form 3 books plus PMR books.  I was hoping that we can pass down the books to someone who really need it instead of jual timbang kati..Infact there are tons of books in the store..I just need the mood to do it...
