The Game is not good at Math.

Be careful on the Marketplace and on Contracts.

Look at how much you are paying to send something to sell and look at your total prices.

Remember for the Marketplace and Contracts, the Game is not good at math, do not use commas at all, and only use a decimal when you have to.

You can loose lots of Gold quick sending something to sell if you are not careful.

I'm sorry to say but this is hilarious. The game is very good at maths, the problem might be with the user.
Do not worry about the decimal point, use the one from the NumPad on your keyboard and you'll be fine. In addition, read the confirmation message just before selling something to confirm it is indeed the sum you wanted.

Cheers,
