The International Association of Exhibitions and Events warns exhibitors of The World Business Guide, a product of International Directories Group, Ltd. of Madrid, Spain. The company invites businesses to list themselves in its database. The form used to gather contact information says in part, "(Updating is Free of Charge)" in boldface type.
However, embedded in a lengthy paragraph labeled "Order" - in very small type - is a binding three-year agreement that automatically renews every year for another year at a cost of € 995 (about $1,455). Dating and signing the Data Control form will bind you to the agreement.
