–Many of you are using PBS-DC, with great results! Typically, senders are getting their credits the day after mailing the book—some within just hours. Even for those few packages unscanned by USPS until delivery, senders are STILL getting their credits faster than they would have. **Remember that using PBS Delivery Confirmation does NOT tell the system that the book has been mailed. You still need to click that button “Book Has Been Mailed” before the deadline on the transaction, to tell the system (and the requestor) that the book is on its way!
