Abstract: The invention relates to a logistics system and to a method for selling goods, wherein within a display area, goods are presented; an individual PIN is allocated to each customer; goods selected by customers are conveyed to at least one intermediate storage area by way of a transport device; the goods belonging to a particular customer are identified by verifying the PIN and are conveyed to at least one storage area which is reserved for this customer; and after payment and collection from the storage area in the intermediate storage area the goods are handed over to the customer in a goods collection area. Known methods are associated with the disadvantage in that the customer can only select generic goods.

Abstract: The use of an azo pigment of the formula (1) ##STR1## as a colorant in electrophotographic toners, electrophotographic developers, powders and powder coatings, and electret materials, wherein said azo pigment is prepared in the presence of 20 to 50% by weight of an auxiliary selected from the group consisting of a rosin, a salt of a rosin, an abietic acid, and a salt of an abietic acid, wherein said weight is based on the overall weight of the azo pigment including said auxiliary, and wherein the azo pigment has a specific surface area of more than 70 m.sup.2 /g and the azo pigment particles comprising the azo pigment have a length-to-width ratio of on average less than 2.8:1 and a mean particle size d.sub.50 of less than 130 nm.
