I remember something that I did myself, First town buy Max carrots from Iola, Sleep in the inn for three days sell the moldy carrots for a huge profit. Rinse and Repeat. More tips for this is to use as many warriors as you can for the sheer amount of carry weight --- GT:Kitty Takuto
GO to the starting town, hire too burly warriors, load every one up with carrots, sleep for 3 days, then sell moldy crrots, for 2x profit. Yo make about 200-300K each run. --- If you don't like the smell of pigfarts, stay out of the pigpen.
I'm doing the carrot trick at the moment. Three of my party are women and the other a big burly warrior. I'm spending around 90 000 gold a time for all the carrots they can carry, sleeping three times at the inn until morning (very fast if you turn connectivity to offline in the options) then selling all the moldy ones for 290 000. That's with the gold idol in my Arisen's inventory.
Surprised more people do not know about the moldy carrot trick. Just go to Iola (In starting village) buy carrots (Make sure to have a pawn with Suasion for more money), sleep at Pablo Inn for three days, then sell Iola the moldy carrots, profit!. You can get around $300k each time!
