Wanted bookcase - $10 (Lihue or Kapaa)

I’m an elementary teacher and just got 7 boxes of paperback books to use for my students to borrow.
I’m hoping to find a cheap decent press-wood bookcase to put them all in.
Please let me know if you have an old one to sell to me for $10 or to donate to my classroom.
Crossing my fingers.
Thank you.
