Apologies if the sound just isn't working on my system, but I fail to hear any notification when I buy/sell something--I just see my balance go down.

It'd be nice to hear a 'coin rattle' or something similar when selling/buying an item. No doubt one of these days I'll accidentally hit a button, buy a huge item, and have no idea until I find it missing and/or see my wallet was cleared.

Am I only the one not hearing anything?

I hear sounds when I buy and sell things, but only if I click on the buttons with my mouse. If I use my keyboard, then I hear nothing.

Ah that must be it then, I'm using a gamepad. Strange. Wonder if the mouse actions are binded to sounds while the keyboard is not?
