I was wondering how much this function gets used. I use it not only to track books I send to friends and family members (totally outside the PBS system) but also whenever I do a deal that includes a free book--- I think I still get a tick mark for number of books mailed that way and it gets recorded in my transactions.

Yes. I now use it for deals to get the books into a bulk mailer, game mailing (though I haven't played a game in ages), sending unpostables -- anytime I need to send a book that isn't getting a credit. I can print a label that way sooo much easier.

I don't use it frequently, but I like having the feature for when I do need it.

I really love that I no longer have to remember to delete those deal books.  Adds an extra step to the deal, but gives a label with the book list, postage,  and deletes the book from my shelf.  Rah!

I've used it a couple of times.  I don't use it often, but I like the option being there.

Yes, this is a nice feature on this site :)

I use it a lot as I exchange books with friends. Then sometimes I use it when I just need a printable postage label. I've used it for unpostables and deals just to keep track of the books.

I use it when I need printable postage for small packages that go first class (I just pick any book and then adjust the weight downwards).

I used to use when I mailed game books but I don't play the games anymore.

Where is the "mail to a friend" feature? I don't offer deals often but when I do it sounds as if it would be exactly what I need!

Barbara - find the book you want to send in the system.  Click on "More Options".  Mail-to-a-Friend is the last option.  I use this all the time for books I send out in the games.
