Bonanza Weapon Kupon Question

Pretty sure I know the answer to this - but during the return home campaign I logged in on each of my characters and grabbed the bonanza weapon kupons, but didn't redeem them for the actual weapons.

So question - does the bonanza npc stick around to redeem the kupons after the campaign is over, or do I need to redeem them now? If they disappear, the kupon will work at another bonanza date when the npc reappears again?

I thought the dealer moogle was permanent.

I think it works a bit differently with pearls because the numbers change, but you should be able to use the kupon whenever you want to.

The dealer moogles dont disappear

The bonanza moogle will disappear, but thats only for buying or redeeming bonanza marbles.

I have other kupons from old Bonanzas and you don't have to redeem them. The dealer moogle reacts to the kupon long after the redemption period (because the kupon itself is the prize). This is also true if you've convert the Kupon item to a key item. (You can do this by trading the Kupon to the dealer moogle and deciding not to pick a prize. Your Kupon will be converted to a KI).

I would bet my money that these Kupon MOGB items behave the same way.
