Verify retailer and after-sales support
Check the brand's official locator and ask whether the retailer is authorised for the exact category. Confirm local warranty, repair intake and return terms before purchase. Keep an itemised invoice and the product reference.
Choose for local use
Warm, humid periods and heavy rain affect leather, watch straps and storage. Try clothing and shoes in person, compare centimetre measurements, and think about commute and storage conditions rather than relying on overseas size labels.
Take extra care with pre-owned goods
Ask for an item-specific report, detailed photographs, repair and alteration disclosures and a clear return path. For jadeite, pearls, diamonds and vintage watches, seek specialist documentation appropriate to the material or movement.
Check travel and import rules
If a purchase crosses a border, confirm current customs requirements with the relevant official authority. Rules and exemptions change; do not rely on seller estimates or old travel advice.
