Read the written warranty and return policy before purchase. Record the coverage period, exclusions, claim contact, return deadline, restocking fee, and who pays freight. Keep the receipt, listing, packaging, labels, and installation record. Verify the final application and written terms with the part manufacturer, seller, or installer before purchase. Separate fitment risk from price risk so the reader can decide in order.
