Please bring back expired SE store item code items!

I have a couple codes I forgot to use from items purchased when they came out and they are now expired. :( I see you have already brought back some item codes for other old items that came with a few of the plushies. I would humbly request that you please bring back some of these other items such as the first encyclopedia and arrangement album soundtrack (Duality). I would even be willing to re-purchase these products in order to get the in game items I missed out on by forgetting the first time around.

(even better would be if you allowed a "forgiveness period" to use some of these old codes which we legitimately purchased but forgot to enter, however, I don't see that happening...)

Many of us are very loyal decades-long Final Fantasy/Square Enix fans and pride ourselves in our decades long collection of both real life and in game items. It is disappointing to be a loyal collector but because of one or two screw ups, you have permanently missed out on some items.
