Well since everyone is allowed to think for himself...

I will sell an item for what I think is correct. If I see a fire/wind/lightning cluster for sale for 2k, I will sell mine for 200.
Because I think 200 is a correct price for someone who will craft something & 2k is retarded, and the greedy bastards should stay in their cave.
Granted, some rich guy may buy all they cheap things I sell and then sell them back at a price 10 times greater.
Still.
If I think that I will help some guy level his DoH or get his new piece of armor, then that makes me feel good, and I will chose not to get rich.
I currently have ~90k gil.
