since you asked:
1- your starting bid is above market price.
2- your Buy it now is above NPC price, so nobody will make any profit from using it.
3- rigth now the selling price average of Gas to NPCs looks like a rock trown in the water.
@Drummore I didn't ask anything but as you remark:
1) I am free to set the price i want
2) There's no NPC selling gas
3) there's no Q5 gas on the market right now and price for Q7 is between 20 and 25
