Funny thing is I have noticed buyers picking out cartwheels from rumage boxes myself , even the ones in the poorest condition sell for £1 or so , I am not sure why these buyers want vast collections of low grade cartwheels , personally i would run a mile if someone wanted to show me his collection of low grade cartwheels .
Take all sorts I surpose , surely they cannot be buying them as an investment .
There again you often find that the thing nobody considers as an investment turns out to be the best investment.
Certainly anything marketed as a "good investment" immediately raises my suspition that it will not be a good investment
