Overview
Code 66 deductions are related to markdown monies and price protection agreements between Walmart and suppliers. These deductions are typically based on negotiated agreements documented through Retail Link, Co-op Agreements, or Online Supplier Agreements (OSA/GSM).
Suppliers should review the applicable agreement details and confirm the deduction with the sales representative who approved the arrangement. The invoice number associated with the deduction represents the co-op number.
Code 66 deductions should be verified against approved supplier agreements and supporting documentation before determining whether a dispute is appropriate.
Common Root Causes
