Also, some materials drop so frequently from mobs that you can get them just as cheap or cheaper on the market board. If you're deciding whether something is worth cluttering your retainers' inventories, check the vendors and the market board to see how much it would cost to buy back later, when you actually need it. If the cost would be no big deal to you, get rid of it. For example, is having to spend 1,000 gil (or 5,000, or whatever amount) worth it to free up an inventory spot?
