It's not much really and the money goes to a good cause. Thats how I look at it because I love this game so much. We have bags to keep at least 1 completely separate set of gear for everything DoW/DoM/DoH/Dol. There's the armour if i'm spelling that right that holds seasonal, promotional, quest items.

There's more of a bonus too than just more inventory space. You get to marketboard more things and you can make several million gil quickly from retainer ventures. Selling minions, materials, and materia and with the 18 hour venture they bring back 3000 or 3500 gil of allagan pieces each time.

Get 1 more and if you don't need it later or the next month. When you cancel paying for that retainer it still keeps everything, gil, items, levels, gear. So you can long term storage stuff like that if it comes to it stuff a retainer full and the next month cancel it till you need that storage stuff again.

Just an idea!
