AliExpress offers a comprehensive return policy to ensure customer satisfaction. If you are not satisfied with your purchase, you can open a dispute within the buyer protection period (usually 15-90 days after the order was shipped). Once a dispute is opened, you can request a refund or a replacement, depending on the issue. AliExpress will mediate between you and the seller to reach a fair resolution. Always read the seller’s return policy for specific details, as individual policies may vary.
