Partly thanks to the recent sale, more supplements have recently reached a best-selling level.
On DriveThruRPG, 100 Creepy Things and Events to Encounter When Travelling and 100 Zombie Encounters for the Zombie Apocalypse have both gone Copper and 100 Rumours to Hear in a Town or Village has moved up to Silver.
On RPGNow, 100 Frescoes, Mosaics, Murals and Reliefs to Find in a Dungeon and 100 NPCs You Might Meet At The Tavern have both gone Copper.
