Prices are back around where they were before the traders all went nuts with the sell price going through the roof and the buy price going down to vendor prices.
If that stays the same black dye should stabilize back around 9k and silver should hover around a plat. People are happily buying at that so there's no reason the traders shouldn't reflect that market.
Prices will rise. The economy will turn into what it was before the Black Tuesday price skyrocket. You should have bought everything when prices were reset and were at an all-time low. If you didn't, or were too poor to, you're like me and got f***ed over. Again.
But at least now I can TRY and afford... something...
Prices will generally go down... There's incentive to sell to NPCs now so stock will naturally go up. And thus, prices will slowly go down and closer tie into supply and demand, as opposed to the old system.
