You can acquire Yojimbo at a discount. Typically, you must pay 250,000 Gil, but you can instead pay closer to 194,000 by following this process. First, save your progress so that you can start fresh if you need to. Then answer "To defeat the most powerful of enemies" when you visit the Chamber of Fayth and the Fayth asks what you seek. The starting price for Yojimbo is then set to 250,000 Gil. When you make your offer, though, suggest 125,001 Gil as the price instead. This will lower the actual asking price to 225,000 Gil, at which point you should counter with a new offer of 125,002. The new offer you'll receive is 205,000 Gil. Increase your own offer yet again, this time to 150,003, and the new asking price becomes 194,000. That's as low as the price can go using this process. If you try to make a low offer again, the transaction process ends.
