No, but I reckon we both have a keen appreciation on the value of a dollar. And I don't have 20 bikes rattling around my back yard. (just putting in a good word for golden6. There's always hope!) But alas, I do have a lot of polystyrene vegie boxes I have dutifully collected from IGA over the past couple of years. Hubby thought I was collecting them for his seeds but I had a higher purpose for them. I read that it's possible to insulate under timber floors with polystyrene so I thought I was on a winner, collecting to my hearts content. But alas again, when hubby finally mentioned that we didn't need any MORE boxes for seeds I filled him in on what my plans for them were. Didn't realise that they were a fire hazard and that the commercially available ones were sprayed with fire retardant.
