When a Pango user adds your listing to their cart, it means they're interested in it! Some buyers may be waiting for their next paycheck, a lower price, or for you to add another book they're interested in to check out. When a Pango user adds your book to their cart, it still remains active and available to purchase by other Pango users.
You can promote your listing to potential buyers by lowering the price by $0.50 or more, which triggers a push notification to any interested buyers who have the listing in their cart or wishlist!
