- Chargebacks occur when a Walmart customer disputes credit card charges with their financial institution for purchases made on Walmart.com.
- Chargebacks may also be referred to as "charge disputes" or "credit card reversal," and may be initiated for various reasons.
- The Walmart Marketplace Retailer Agreement provides that sellers are responsible for all credit card chargebacks (other than those relating to credit card fraud, for which Walmart is responsible).
