Dear Steam User,
Steam will soon be priced in Thai Baht!
If your Steam wallet has any money in it on September 16th, 2014, your U.S. Dollar balance will be converted to Baht, at a conversion rate dictated by market value at the time of conversion.
To view your account balance, simply log into your Steam client or the Steam website at http://www.steampowered.com. Once you have logged in, you will see your balance in the upper-right corner next to your account name.
Thanks,
The Steam Support Team
