- Roulettes. Especially as a PLD, WAR or DRK. You don't have to do them all everyday but even doing a trial gives you 10,500 gil outright and if you're going as a tank then you get a slight bonus on top of that.

- Ventures. It's hit and miss as to what your retainers bring back but I've had them bring back furniture and dyes that sold for a considerable amount of gil. My record so far is a rug that sold for 6.5 million.

- Hunts. Try and find an active linkshell that calls out hunts. 4.0's hunts have a chance of dropping a cracked cluster, which can be traded in for level VI materia. That's a great way to earn gil as high end materia usually sells for a decent amount.

- Challenge log. Don't bother trying to do everything on it. Pick out a few of the easier things to do each week as you can get a bit of gil that way too.
