Dropping the price of your existing listings is a great way to get the attention of potential buyers. PangoBooks pushes listings with new price drops to the top of the feed in the app, with an icon indicating the percent recently discounted.
The requirements for your listing to be reshared are as follows:
Drop must be at least $0.50
Must not have been dropped in the last 12 hours
Must not have been dropped within 12 hours of initial listing
Only 5 drops are re-listed for a user in a 24-hour period
