Please help me, Im new here and I apparently mixed up the address's on the boxes so 2 members got the others books. How do I recify this problem, Whats the best and quickest way to make it right

Welcome Michele. You're not the first one to do that. Here's how the site says to handle mixing up the address on shipments along with the link in the help section:

If you mixed up two requests and sent the wrong books to two people:

• Contact both requestors.
  • Use the buttons on the active transactions for the books to let them know what happened.
  • The active transactions for books you have mailed with be on the Books I've Mailed tab, in My Account.
• You can ask the requestors to send the books to each other
  • You provide the addresses in PMs.
  • You should also offer them each a credit or postage for sending the book to the proper destination.
    • You can gift the credit using the "Give credits" button as described in How do I give credits to other members?
    • Alternatively, you can send postage by snail mail
    • Or, you can send postage by PayPal if both of you use PayPal and agree to that.
• When the requestors get the books they requested, they can mark them received.
  • This means the sender "breaks even" on these transaction, but each book ends up with the person who requested it.
• If the books are delayed enough to have been declared lost at PBS:
  • the requestors can still mark them received when they get them (giving you credit) from their Transaction Archives, as described in I received a book that was 'lost in the mail'.
• If either of the requestors marked either of the books received with a problem, you got credit at that time.

If you can't get the correct book(s) to the correct person/people (one or more of the recipients does not want to send it or is not Responding to your messages, or the mis-sent book has been damaged, or you never actually had the correct book, etc):

• If the book(s) is/are not yet declared "lost in the mail" - you should contact us to cancel the transaction.

• • This is better than waiting for the book to be declared "lost" by the system because it gets things moving faster  - the request will be passed to a new sender if there are other copies available when we cancel.
  • It is also better if this is a Wish List book - because if we cancel and there are no other copies in the system, the book will go back on the requestor's Wish List  in the same position as before.

• If the book(s) have been declared "lost in the mail" you can just leave things as they are - they can repost the books to their own Bookshelves.

  • If the books were Wish List books, they will be offered to the other member (if the other member is not already getting a copy from someone else)
  • If the books are available in the system, the requestors can simply re-request the books from other senders, with the credit they got back when the books were declared "lost inthe mail."

Note: The best way to avoid mixing up requests is to:

1. Before printing, be sure to check the title of the book you are printing the address for on the top of the Wrapper Settings page
2. After printing, check page 2 of the wrapper to ensure that the correct book title(s) are listed there.
3.  Before Wrapping, first match each PBS Wrapper page 2 (which has both the address and the book title on it) with the book, then match page 1 (with the address on it) to page 2 (which also has the address on it, and which you have already matched to the book).

Hopefully, the members contacted you before they marked the books "received with a problem". If the packages are both still on your "Books I Mailed" tab, that is ideal. You have NOT yet received the credits for the book packages at this point.

You would ask each member to forward the package to the other member (message the other person the correct address). You would compensate them for the postage to do so (usually by friending then a credit (or two, if the boxes will cost more than standard media mail postage)), but it could also be by mailing them stamps or a check or whatever you agree on with them.

Each person marks the books received when they get the correct package, so you get the original credits for mailing the books  ... both of them have been made whole, and you are only out the "extra" credits to compensate the members for the extra postage they paid.

----------------------------------

It is a little more complicted if they other members already marked the books received (and they are not on your tab anymore). In this case, you have received the credits for the books. The easiest thing to do at this point is just to refund the credits, in my opinion, and let each member re-order the correct books themselves.

But if you really want to fix it, you would do the same thing, basically, hold off on any credit refunds. Ask the members to mail each other the books. When they get the correct books, they let you know, and at that point, if they are happy (the books are postable), then you keep the credits that you already received. If they are unhappy (feel the books have some other problem or whatever, you would have to work with them to refund the credits or whatever)
