Yeah it is, but sadly true on apoline. Xir 3 sells for 7 - 10s each D:
The market on Apoline is wacky, I see some things leveling out though. I can at least get Vit3 and Def3's for 6-7s each now instead of 10s. I think because it's one of the newer servers and now that there are alot of higher lvl char's playing and producing. Demand out weighs Supply on alot of things here which dictates a much higher price. Also they have made it much harder to Farm High lvl mats by moving them all and making them a little more rare and increasing the price because people are buying instead of farming.
