And by the time you come back from checking the average price in wards I teleport out to Mor Dhona and then you /t me saying you wanna buy and I'm like "Oh hell no, you come over here I'm not wasting anima again!" and you're like "Oh hell no to YOU, you're not worth my gils!" and then we blacklist each other

Actually it kinda sound like fun xD
Anyhow, even if the perfect system was created I'd say at least 50% of the player population would use it in a way that would tick off people - as in, not "perfectly". Bit sad knowing some people will always be frustrated about this

The point is valid, and it would really be nice if bazaars in general worked better, but if this "problem" is always going to be present (as I think it is) and it ruins a part of their enjoyment in the game, then it really is bit sad, without any sarcasm.
