So today I was selling some books I noticed that I sold 4 in total, 2 for 10m each and 2 for 5m each, so that gives me 20m right? I checked my inventory and I had same money as I started shop with and books were gone, you may say I put the wrong price, I tough same too but than I checked those "!" and it said that I sold in total 4 items I checked prices there and they are were like I set them.
