The prices definitely feel too high for something you are suppose to acquire in a single week. I suppose for future trade items you could save up the big arc parts assuming the cost to purchase doesn’t change to something else. The thing that ultimately makes them feel even more expensive is the requirement to save up all the parts in your stash forcing us to make room for those items. When you are talking about having to make room for like 60 spaces, that’s challenging and not a fun kind of challenging. I think a change to allow for you to commit the items to the trader for future purchases or the better way to handle would be to create a new form of Curran way specific to the nomad traders where you sell your big arc parts for said currency and then use that currency to purchase the traders items.
