This volume deals with the problems caused to businesses by "scam merchants" who seek to extract money in return for goods or services of little or no value. The scams described include entries in directories sold in a misleading way, office consumables promoted to unsuspecting junior staff at outrageous prices, international advance fee frauds, "consultants" whose services are worthless, charity donations being misdirected and a range of "borderline" scams such as phone and fax line services charged at premium rates but of questionable value.
