Hi everyone, I was hoping someone can point me in the right direction on this. Ok so I have a couple of books that are in a series, they are both wishlisted, that I would like to send together. I don't have them on my shelf because of this. So where do I go to post these together so I can save on shipping? Thanks 

In the Love/Romance, Paranormal and Mystery/Thriller forums (maybe some of others)-there's an ongoing thread called Is This On Your WL?-where you can put the books you have and aks for someone who wants both. I do this frequently when I have multiple WL books from a series, author or even just several WL books to post at once. 

Also when I post a WL book or someone orders a book off my shelf: I check their WL to see if I have anything else in my TBR that I can post to them. I've only been turned down once to someone who was a stickler for FIFO.  But finding people I can post multiple books to allows me to send out more books and make more WL lines shorter. So if no one takes you up on the offer in the genre thread-you could just post book 1 and chances are good that they might have book 2 on their WL as well.  Maybe not but possibly.

Thank you

Good advice Mary, I've had success with both methods :-)
