Is it worth doing them ?

If the item/s are cheap enough, yes, same for any quest really. I don't usually do them though. Much prefer my Wizard and Saggi quests.

Ok just thought i would try them again. Last time i ended up spending so much on them. Thanks for the fast response .

moved to quests.

for me they are worth it because they give me a lot of sp but i hate the saggi quests, to expensive and I never really got anything out of it(thats just me) It all depends on what you get and how much the item is worth.

They are worth it if the items aren't to expensive, because you may end up spending more than you get and that is just pointless.
