Basically just asking if it would be possible for the staff to make it so shop signs work on barrels too. Love yall!
Assuming PF uses the ChestShop plugin, this can be added by changing the config. "Barrels should work already (at least in the latest 3.10 builds) by adding "BARREL" to the "SHOP_CONTAINERS" list in the config." - Pheonix616 Resource Staff Spigot - ChestShop | Page 13 | SpigotMC - High Performance Minecraft
