How much $$$ before you get the wife's approval?
Many years ago when my addition started with with pumps and signs my wife thought I needed therapy and I probably DID. I have never used any of our income from work or savings to purchase anything for my addition.
I have a great and loving wife who now stands with me at auctions and has seen and shared the profit from it. I have had to pass many of great deals due to not having anough money availible. Family has always been the most important thing in my life . My addition in gas and oil is fun and my wife has never told me not to make a purchase when she knew I wanted it and I could afford it.
