Any items which sell well from the Kafra shop without a condition attached?
No buying cash shop equipment to sell. Noted.
Kafra shop equipment are also good, as long as you keep the exchange rate high enough. Usual rate seems to be 10m / 100kp. So if you're buying a 500kp item, make sure its selling for at least 50m. Be sure to check Ragial for the current exchange rates, if they are below the said rate then its most likely you'd make more profit selling something else, don't buy robo eyes for 500kp if their ragial price is 40m, when you could easily get 50m for 500kp from Heavy Lifter Box. Best ones are the ones that have been suggested before, that everyone will need at some point and combining that to the right spot to sell at. This means standing next to Ripped Callus with heavy lifter box on sale or selling Enriched's at the 2nd floor of eden when Enriched Hammer is on. I would say you could easily pull off a (bit) higher exchange rate on items, when you're conveniently positioned. Silvervine near Malandigo enchanter, Omni dye near the dye NPC etc. The key to selling Kafra Shop items however is patience. Don't undercut too much and ruin everyones gains, if there is a guy selling 10 Heavy Lifter Boxes for 50m, don't set up a store selling yours for 45m, but instead use the positioning to your advantage and don't undercut. They will get to your box eventually.
My suggestion to buying low and selling high is to always buy items you need yourself. This means, that if you're a mage class (or you have a mage alt), buy things like orleans's gowns, bradium earrings, tsod and necromancer cards and then vend those for a bit over their market value. Do not buy too many though, having one gown/earring in circulation at a time is the key. It helps, if you're the only one selling the said item of course. The key with this technique is that no money is wasted. If you do not sell the item, you still got the one you need. Got an assassin coming? Buy Sapha gear that you would use yourself and then vend it for a bit higher than what you paid for it (best would be to find one, that is grossly under the market value at that time). By the time you hit GX, you'll either have a shiny, good Sapha gear to equip or decent profit. Basic point is to never buy anything you can not use. Buying an expensive (but useless) item in hopes of profit rarely pays off. Don't waste your money buying a +12 HF if you do not play a merchant character, since if you can't sell it, you'll only lose.
