Cosmetic question

If I buy the commemorative head screws for 700 Aquilas from the ogryn set. Then I want to buy the rest of the set later how dose it work if i already own a item or items from that set? dose it still cost 2400? is it 1700?

Unfortunately no, the price won’t update to reflect what is already owned… This needs to be changed, and it’s on our to-do list.
