The Product List and Catalogue display the highest and lowest product prices offered by GDF's principal suppliers. For most products, GDF maintains long-term agreements with multiple suppliers, with target market share allocations depending on supplier status (primary/secondary/tertiary/quaternary). Allocations and supplier status may vary depending on performance, product status and other criteria monitored by GDF and its Procurement Agent. GDF and its Procurement Agent also hold contracts with back-up or auxiliary suppliers and occasionally, products from these suppliers are offered to clients. Prices of these products may deviate from the range shown in the Product List or Catalogue. 


For budget purposes, GDF clients are strongly advised to utilize the highest product prices displayed in the List.
