Here, check this out, an ebay listing for a very good idea and at a cost where all proceeds go to the Haiti appeal ;

I paid a quid for it, and it is just superb I am definately going to do it, as the cost of making is minimal, possibly less than five quid and the saving it provides, like wow.

But if anyone should take my recommendation and buy this idea, please don't make the idea public, for the cost paid is for a very worthy cause and I would not wish to see the appeal deprived of funding because of a misguided idea about letting the world know the idea for free.
