A prospective seller participating in your RFP, Acme Anvils, calls you to discuss the pricing contained in its proposal. Acme is also a large customer of your company as well as a long-time supplier to your company with superb performance in the past. You would really like to see Acme win the business for your project. As the Procurement Manager, you have visibility to all of the pricing provided by other prospective sellers. During the discussion, Acme asks you for guidance on their pricing so that it can be competitive with the other sellers. How do you respond to Acme's representative? If there's an issue, identify that, too.
