I have a big set of Handwriting Without Tears books: instructor guides for PreK, K, 1/2,and 3rd grades, as well as the student book Get Set for School.  But I also have the manipulatives:  wood pieces, letter cards, mat, and chalkboard.  I wasn't sure if I can list it here since I have both books and manipulatives?

Thanks!

You can list the books here.  I'd personally list the sets over at HomeschoolClassifieds.  If any of the manipulatives have ISBNs, you can try posting those here.  I had some algebra manipulatives that had a number and was able to post them.  Otherwise, you can't enter them in the system.  You could make a deal with someone (in our HS deals thread) that if they order X number of HWT or other books from your shelf (in order to cover the cost of shipping), you'll throw in the materials.  However, you cannot send the manipulatives as Media Mail, so watch out for that, as it will drive up your costs to mail.

there is someone wanting the set of mamipulatives, slateboard, etc right now

It may be worth your trouble to still mail the books media mail and the rest separately. But only if all the books you are mailing weigh less than 13 oz total.
