7th Day Market

Prices for items flutuate wildly along the sunday (when you buy) and along the other days (when you sell).

Yeah, just make sure you check the prices every hour.

Only problem is that the items don't stack so your profit is quite limited.

You could simply use multiple characters to hold onto more items. That's what I did when I even bothered caring about 7th Day Market. :f6:

Oh, and to be completely honest with you, this is not the best way to make profit. You'll make an average of ~300k mesos profit per week on each character.
