Thanks you guys and lady <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
I will sell amulet and purple potion. BTW, I saw something stackable can be increased by entering negative numbers while dropping with CRTL key. I increased cure potions by this way and made a lot of them. (When I enter -1, I end up having 3 in my inventory and 255 on the ground.) However, now I can't use any of them because the 3 ill NPCs don't seem to recognize that I have cure potions for them. Any comment on what I am doing wrong?

And another thing; I gave money to the poet in front of Kistandalius' shop. But I didn't know the use of it and didn't steal from him. Now I can't find the poet. What can I do?

Also, I am playing a level 40 mage (Battlemage) now and I have 13 skill points available. I can't choose from following:
1. Elemental Strike, Seeking Flame, Summon Demonic Aide+Master Summoner and Life Leech.
