Donations at FlyFF ProGM are completely voluntary and will always be based on all consideration to keep the game online. As part of our generosity, and thanking you for the contribution, credits will be given to obtain items on the web. I remind you that when Buying virtual objects on the web, this is still a virtual currency, but donating is a great help for our server. In addition, the refund of the money is not made if you are not satisfied or made a mistake, that is why you must be very attentive and sure in what you do.
