You can ask in all chat for a price check, a static price list would be the worst because of inflation, demand and offer and personal preference of a single and all players. The prizes changed a lot in the past, from 100k to 1 million to 300k like right now, when you sell your item under its value its your fault, its easy to find out the right value.
Also staff wrote smt about that at the suggestion forum. You have to scroll a bit, there is a headline "Price of MS or Inflation".
They say they wont change anything about that.
