Key Proof:

• Receipts: Prove "what receipts prove credit card charge dispute"--must match description/amount.
• Emails: Order confirmations, refund promises (verifiable via headers).
• Photos: High-res of defective items (e.g., broken gadget vs. advertised).
• Tracking: "Not received" needs delivery failure proof.

Mini Case Study: Sarah ordered a $450 laptop online. Evidence: Email order confirmation, undelivered tracking, photo of empty porch. Merchant claimed delivery--her Ring doorbell video won the dispute.
