It is, indeed. You need to check Giran’s special NPCs. Woodley, Woodrow and Alexis (along with both Mammons) … Anyways, Woodley (if I am not mistaken, might be Woodrow) is selling all consumables, along with quest items and some other stuff. All these NPCs can be found in Giran center and next to the stairs, where GK is. If you do not see them, I would recommend using Updater again before logging back in. Might be there was a problem when you did the first updating and some files were left out. You can also PM in game for any extra help.
Good luck! 🙂
It is not that you do not understand, it is that you do not even question.
