.....it's usually how much the seller wants to part with it for if there a honest, helping person, not who can give me the most for it, that's greed
anyways, you can hunt photon crystals on easy in ep4 with ease, 3 or 4 in 20 mins solo, use them in BPD quest and get a smartlink for 30 mins time for free and not pay out the @ss from someone, when i had them in my store, i sold them 2 for 1pd, but then again i dont have greed issues.
