Good afternoon, I work with a company that buys about 50,000 empty virgin cartridges a month. We are in the process of incorporating here in Florida and plan to double the purchases volume by July of this year. Please let us know if you can help us do that. Until we have a purchase history with our new suppliers we pay upon shipment. References are available upon request. 95% of the purchases are HP models: HP21 HP22 HP27 HP60 HP74 HP75 HP92 HP93 Best regards, Jeff Romais 954-708-0597 I want to receive: Product Spec .
