Does anyone know the optimal buying/selling percentages of normal, increased and decreased-priced items to get the maximum experience points (high chance of pin bonus and customers should accept at first offer - no haggling; to get the maximum number of Just Combo bonuses possible) for each customer in the game (including Euria) while making profit as high as possible (prioritize experience)?
I have just finished the game and I am now trying to reach a high merchant level while trying to make the item inventory well stocked with items so I can play a 'New Game+' easily to get another adventurer's True Card.
Also, I would like to know the optimal buying/selling percentages for maximum profit, while making the customer not haggle and making the experience as high as possible (prioritize profit over experience).
Capitalism, Ho! Y'all!
I found a Pin Bonus guide here: http://recettear.wikia.com/wiki/Pin_Bonus_Percentages but the data for some of the customers are missing (some are even wrong), and there is no data at all for decreased-priced items. (Although this maybe because it was written for the demo version of the game.) I am playing the Full version with the current latest v1.108 patch.
The 'always-sell-at-104%' technique mentioned in the link I put above and FallenAngelEyes' link in the comments works fine for getting maximum experience points when buying normal-priced items. I was wondering if this could be increased for some of the customers to get more profit while still maintaining a good chance of hitting the Pin Bonuses and Just Combo chains. Also, I need optimal buying/selling info for Euria, who was probably put in the game to break Just Combo chains. I also would like to know the elusive buying/selling info for increased-price and decreased-price items for all customers.
