so i noticed that even if i already have the items required for the quest in my inventory or bank, as well as any suggested items then the quester will still deposit everything to the bank and then pull out money to rebuy all the items needed and suggested for the quests... also, for dragonslayer 1 it will buy armor even if you already own said armor.. its a waste of GP honestly (lucky for me i purchased bonds to sell so I have a few million GP, otherwise it would have burnt through all the GP i have made). i have a set of rune armor with a rune chain, as well as a full set of adamant armor and it still went to the GE to purchase another set of adamant armor.
