I agree with you, its nice to see older event items be available to people, but having 10 gil items up there for over 2 euros/3 dollars each...for just a hat? I'd say price them between 0.50 and 1.00 and id say alright. Not to mention that 3 of the items currently in the optional item shop are TRADEABLE if someone that did do the event gets them off their calamity salvage npc for 850 gil.
