Correction of prices for optional items

[Felis]

And event items were purchasable in-game before. They always came back around the next time for purchase.

Only during the first year of ARR.

That they sold old event items in the evnt vendors could be to give people who never played 1.x still a chance to get it
And with the Yukatas last summer event, there is no 1.x seasonal event gear anymore that still need to find a way in a ARR seasonal event
