Walmart Code 12: Price difference between invoice and quote or price list.

- A temporary promotional quote was applied to a standard replenishment PO
- Item master pricing in Retail Link was not reverted after a temporary price reduction
- Buyer entered a quote that conflicted with the formal EDI 850 PO price
- Pack-size or inner-pack conversion discrepancy
Documents that win.

- Signed quote sheet or promotional pricing agreement showing valid dates
- Buyer email or Retail Link item cost history proving the quote expired
