Hello. I'm hoping to get some help on how to set the profit margin and re-purchase prices for a basic merchant. What I want to do is 1) Set the price the merchant pays for an item to say 10 to 20 % of the items value, and 2) if the player chooses to buy back an item before leaving the merchant, the player only has to pay what they got for the item (e.g. player sells a sword for 200 gold, changes their mind and pays 200 gold to get it back). Thanks for any help.
