I think we need to see exactly how this grand exchange works before we get set on how it will kill everything and whatnot but I think for sure it will drop prices, because if it works by putting an item in and set it for a specific amount, and if people decide they want it lower, than they'll find another person selling it for a lower amount and the sellers will have to conform to the buyers prices. that's pretty muc already happens now, but I think it'll happen faster with this grand exchange
