I found a ton of books at the thrift store today that are all on the wish list. I would like to be able to offer them to my buddies first is there anyway  to find out who wants the books besides going through each and every buddy?????

Unfortunately, Bertie, there is no way to do what you seek to do.  Books at PBS are offered to people in FIFO order, and sent out in FIFO order when the automated system is being used, and this sequencing doesn't allow for searching for individual members to "jump" the FIFO line.  This is the fairest method for all members to have an equal chance at getting the books they want.  PBS does allow for us to do such "jumping" but it does not encourage us to do it, nor does it make it easy to do so.

ETA:  You could send out a Blast Email to all of your Buddies at one time, with a list of the WL books you have and see if any of them respond, and want to order your books.  That would save you checking each member of your Buddy List individually.

You really can't.  However, since you know who your buddies are and have access to their WLs, you might go through them before you post a book to see if one of your buddies wants it.  You can then post it directly to him or her.  Otherwise, it's FIFO.  I love FIFO. :)

Bertie, I'm one of your buddies.

Take a look at my wishlist!

sorry Gina none of them are on your list

Are you going to read them first?  If not, that's very nice of you to get them for someone else's WL.
