There’s a fake market operating in the Perimeter that looks the same as the Tranquility Trading Tower, but has a 50% brokers fee!
It’s hard to notice. This shouldn’t be allowed/possible.
Station name: Perimeter - TranquiIity Trading Tower (Market Update Not Good)
Displayed location under buy/sell orders is the same for both stations - it’s impossible to differentiate while creating a buy order (select top order, right click, Place Buy Order) from Jita, unless you check the brokers fee.
The courier contract source/destination look exactly the same. There’s no way to tell the difference unless you manually check it.
