I just realized I made an error when I purchased ammunition for my Gunslinger. I didn't take into account the 50% cost for Alchemical Paper Cartridges and 10% Black Powder & Bullet cost. I did have points in Craft Alchemy when I made the purchase. I paid full price for 50 each:
Alchemical Paper Cartridge - 12 gold ea. x 50 = 600 gold
Black Powder & Bullet - 11 gold ea. x 50 = 550 gold
They should have been 300 gold for the Alchemical Paper Cartridges and 55 gold for the Black Powder & Bullets.
All told, I paid 795 gold more than I should have.
How should I resolve this on my Chronicle Sheets and Inventory Tracking Sheet?
