From The What Have I Done With My Life In Aisle 4? department:

The Clerical Medical Group has recently performed a study concluding that the average British citizen will spend over £148,000 and six months inside of supermarkets during their lifetime. I hope they never do a study on how much time and money I will spend in record shops and bookstores in my lifetime. I have a feeling that would be extremely depressing. (Myfinances.co.uk)
