It seems that once again a molehill has become a scientific mountain. The code of the shopping trolley is surely simpler to crack than that.

We've decided to conduct our own survey and we want you to help us.

Our aim is not merely enlightenment. It is also to help all those thousands, possibly millions, of lonely people who each week scour the supermarket aisles keeping one eye peeled for the best concentrated liquid detergent special offer and the other for the perfect partner, to know what to buy, and more important what not to buy, in order to cast themselves in the best possible light.
