Easy Money
Use this little trick to make some easy money and have unlimited access to the best healing item in the game, elixir! To do this, you need to have access to the Thief class (which you can unlock in the first sub-quest) and access to the level 25 nemesis "Mammon" in Norende. Now, when going into battle with Mammon, your goal is not to fight her but to steal her item. Mammon will either have an elixir or an ether. Go in, use brave x4 and steal with your theif, and set all of your other characters to run. Assuming your theif has the highest agility in your party (a safe bet), he/she will go first. Once you find a Mammon that carries an elixir, be sure to hit "protect" on it from the Norende screen. She will always drop the elixir, and as long as you don't defeat her and just keep stealing and running, you can have an unlimited supply of elixirs. They sell for 25,000 pg each, or you can just save them for your own use, as they heal 9999 hp and 999 mp. This gets even better when you get your theif to level 11, as the Rob Blind ability gives you a chance to steal two items, bringing your haul up to 50,000 pg per hit.
Extra Villagers without StreetPass
If you don't have a handy means of collecting StreetPass hits, that can make things difficult in Bravely Default because it affects how quickly you can unlock bonus content. However, you can add villagers to your crew even without StreetPass, provided you take advantage of an opportunity early in the proceedings.
To start, advance to the point in the demo where you receive a quest asking you to kill Adamantite. Before talking to the villager located between the spell and equipment shops, make sure that you save your progress. Then talk to the villager and you'll receive one additional villager. After verifying that your villager count has increased, talk to the Adventurer and go with the "To title" option. Load your save file and you can repeat the process as desired.
The above trick works specifically in the demo, but you should also be able to transfer any villagers encountered in the demo to the full game.
