So, if we have books we want to swap with someone we post the books and see what they have to offer? NO SELL is this correct?
You are correct Khspw, NO selling.
If you have something you no longer want, just post some pics of it and any description you want to add. If someone is interested, they will reply to your post and ask you to mail it to them.
Take a look at the other posts here and see if someone has posted a book you like. If so, just reply to their post asking that they send you that book. It doesn't matter if you have posted any yet, you may post something they want later. It's not an exact "swap", just our way of sharing books (or things) we not longer need.
