Hi, I want to post a book that I have a total of 3 copies and want to show this in my post.  How do I do this?   I don't see any way to show a quantity other than one.  Thanks!

You can't.  You can post the next copy after your one copy has been requested.

I think you have to mark it mailed before you will be able to post another copy.

This is a safety feature so we don't double post a book.  The only way I know to post two copies of one book is by having received two copies.  Such as when a book rolls over or goes lost.  Then you can post both.  Otherwise we have to wait until one is marked mailed. 

This also shows up when you try to order multiple orders of one book.  Can be a problem for folks ordering for home schooling or classrooms.

When I have 2 copies of the same title to post, they never have the same ISBN so it is not an issue.
