How was my buyer able to file a claim before the eligibility window opened?
The guarantee claim eligibility window opens at 3 calendar days after the maximum estimated delivery date for the order, or 30 days from the order date, whichever is earlier. Customers may file a guarantee claim up to 90 days from the order date. However, Amazon.ca may elect to reimburse a customer for an A-to-z Guarantee claim from time to time. In those cases, the claim will be investigated as usual, and the seller will be asked to supply information about the transaction as part of that investigation. If Amazon.ca has elected to reimburse the customer for a claim, and the seller is deemed not to be responsible for that claim, then the seller will not be charged for the claim and Amazon.ca will bear the cost of the reimbursement.
