I've only seen a shout for gil once or twice.

One time when I was in a party we were heading out from Jueno to the Citadel or something, and one of our members asked if he could borrow some gil for the chocobo. It was like 200 gil. Who doesn't have 200 gil? I've had over a million before and I don't craft or farm or anything (and I don't buy it either!).

It's really easy to make money in this game if you are somewhat intelligent. Of course, the way I make money banks on the fact that not a lot of the other players are that intelligent, so there you go.
