I'm working in Dynasty(the company that made the addon) and I get this addon really cheap so that's why I can give you guys this offer =)
I'm selling the gold making addon Tycoon 2 for about 40 $ each. It normally goes for about 50 $ so this is a pretty good price for you.
I'm using this special tool myself and I often make 60K gold per day by just buying and reselling stuff on the actionhouse. This addon gives me all the information I need to make easy profit.
My skype is: 'eliasfurnes' if you are interested
If you end up buying it I will give you instructions on how to use it and help you out. Have a good day!
