When you get to the church, shoot the bell. Every three times you shoot it, some villagers will appear. Kill them, and you will get anything from Pesetas to ammo and herbs. You can do this as many times as desired. This is effective if you have a lot of ammunition or the Chicago Typewriter.
To earn easy money while playing through the game again, carry an empty Handcannon. It costs no money to have, but you will pick up ammunition for it occasionally. This is worth more than any other type of ammo in the game. After collecting the ammunition, sell it to the merchant. Try using the Chicago Typewriter as your main gun while doing this.
