After you've pulled out any books that don't fit the criteria, it's time to pack them up and ship them. The best way to send books is to mail them using the U.S. Postal Service's Media Mail or Parcel Post. These are very inexpensive compared to first class rates. Please be sure to print the Donation Cover letter and place it on top of your book donation.
In some cases, the programs needing the books may be willing to pay for shipping. Contact these organizations directly to arrange a shipping agreement.
