Given the increasing saliency of special offers as a sales promotion tool,
this paper analyses the advantages and disadvantages of the two most common
payment reduction schemes, namely a decrease in the purchase price and a d
elay in the payment of the merchandise. Following some of the latest empiri
cal evidence in the sales promotion field, the model includes a price-depen
dent demand, where price incorporates the ability of the retailer to pass o
n some of the savings to the customers. The integration of both the purchas
ing and the sale implications of the vendor's offer on the retailer's profi
t forms an integral part of the model. A numerical example highlights the m
ain features of the model. (C) 2001 Elsevier Science Ltd. All rights reserv
