First of all, I'm not fond of replacing the PVE que button with Diltihium store button. I prefer to have it back the old way.
But that said, the prices in the store from the button are different from those from the actual vendor (at least on Quonos). The prices from the minimap window seem to the same prices as the crafting ones.
Also, the minimap store is missing the field generator console (the one that was just changed into a sci console).
