Understand Your Consumer Rights for Online Shopping Disputes (USA, EU, International)

Know your rights to act confidently. In the USA, FTC's 2026 guidelines mandate clear refund policies and prohibit deceptive practices; no automatic "cooling-off" but chargebacks protect for defects/fraud. EU's Consumer Rights Directive enforces 14-day returns (extendable for defects) and 2-year warranties. Internationally, vary by warranty claims--e.g., AliExpress offers global buyer protection.
