I will have to disagree on this one, Str Omg123.
The price list in Emps scape was scarcely used, for street prices fluctuated too often for the price list to remain accurate. Also, making a price list takes a lot of time and hard work, and it is most definitely not worth it. That being said, perhaps the introduction of an alch-value list (a list of the high-level alchemy values of items) could be of some use to players. However, as far as a price list goes, the answer (from me, at least) is a resounding "No, thank you".
It was a good thought, though, and it's appreciated.
