This doesn't work all the time but its amazing how much money you can make by just browsing the Market Wards for underpriced items, buying them and flipping them for 100's of k in profit.

Having a large stock of a variety of items that turn over quickly is also another great way to make gil. Inevitably supply will run out for one of the sought after consumables and you sell at a large profit.

Great example: fleece was up to 2.5k EACH on my server the other day. A stack of sheepskin is 99k from NPC, turns into 3 stacks of fleece, that's like 643k profit.

For that matter, checking my server now, sheepskin is selling on the wards for 2.5k EACH. People! Its 1k from NPC! So, just buy a stack for 99k and flip it for 250k. 2 minutes of work for 150k profit. Not sure who buys this stuff.

The trick is that each one of these small ways to make money will never work consistently because of supply and demand. But if you keep 20 or so in your pocket there's almost always one or two where supply has run out and you can make a quick profit for little work. Just takes some upfront investment in learning the market and where to get your mats for the cheapest.

Right now people are paying crazy amounts for dated gear... maybe because its going U/U in 2.0 Alot of it you can still make (its a pain I know) and get some great gil. Or just sell dated stuff you don't use anymore.
