Hi Ming, you could post them in the book bazaar. If someone has all of them on their wishlist then you could post them directly to that person.

It is a bit of a gamble, and seems to work best with numbered series, but you can post the oldest one first, then look at the wishlist of the person who requested it and if they have any of the others listed, post those directly to their wishlist.  You can also PM them and ask if they are interested, if they are have them put the book on their wishlist and then post it to their wishlist.

Another thing is that when you do this (post the books to another's list) and ship them together, you have no way to get the credit assurance for the additional books (if you use DC or PBS shipping). The only way to do the credit assurance is to get a DC for each book and mail separately. So if you want to use DC and/or PBS postage to guarantee your credits, bulk shipping them won't do that, and you might as well send them through the WL FIFO.

Ming - I PM'd you! :)

Jane - I believe that may be true for PBS postage instant credit ( I don't use it so I am not sure) but I know that I have always gotten quick credit for all of the books in a multiple shipment when I use DC.

Melanie, I think the problem is that each of the books will be a separate transaction, because they won't be linked together as one order, thanks to the fact that these are WL books.

Post it in the book bazaar.  When someone responds PM them the exact isbn's and have them add those to their WL, then you can offer them individually to that person thru their WL and then they accept, individually, so you get all 3 credits, or 4 or however many books you have.

When I have WL books in a series like this I  post the 1st one and then check the accepting person's WL.  Almost every time the person has had the others WL as well.  I PM them first to make sure they have credits  because they lose their place in line if they don't and have to decline.  If you use the printed postage you do only get the instant credit and the guarantee for the 1st book sent.
