I think I have spent just over $100. My limit is generally $100 and he'd normally get it as $$$ but this year I have done presents. He is an amateur astronomer so I went onto EBay and got him a Hot Wheels Mars curiosity rover, and a space shuttle with some astronaut.

He also loves the De-Havilland Vampire plane, and our dog had an attempt and chewing his hat the other week. So I got him a DVD on how to fly that plane, a new hat, and a hat pin.
