How does it work when a member is offering a 2 books for 1 credit deal??  Has anyone tried this before? How do you make it work on the site?

You order 1 book through the system, so the credit is processed. Then you send the member a PM with the name of the 2nd book or freebie, and they'll mail it with the other book.

I've done this both as the person offering the deal and as the person ordering the books and it works great.

Welcome to PBS, by the way!

Be aware that the terminology used should be clear. If you're saying 2-for-1, you're saying "two postable books for 1 credit". If you say "Free with Order" you're usually saying that you're giving an unpostable book for free with the order of one postable book. Just be absolutely clear on what you're offering, so the recipient won't be disappointed.

ETA: Unpostables should not be posted to your shelf. They should be listed in your forum post, your signature, or your profile. They also need to be requested via PM.

Thanks a lot for the information!!

It's a good way to earn a few credits while getting rid of some books that are very common in the system especially if you don't want to be a boxer.  It's also a good way to get a few extra books for your credit.  I have a long RL and I don't order any of those books unless I'm getting them as part of a deal. Because there are a lot of copies in the system.  If there's only 1 or 2 in the system, I'll just order it outright.
