Compare Superbuy listings
Take two saved links and compare the same three things for each one. Start with the option you would actually buy, then check fit and delivery cost.
Record the exact variant
Select the size and color on each listing. Save the seller, product link, selected option, item price, delivery to the warehouse and the date checked. Give each saved link a name that distinguishes the two sellers or options.
Use the same fit measurement
Suppose a jacket you wear measures 58 cm across the chest when zipped and laid flat. One listing gives a 58 cm garment width. The other lists a body measurement of 116 cm. Ask the second seller for the jacket’s flat width from armpit to armpit. If you order, request a warehouse photo showing the label and the same measurement.
Compare parcel quotes with matching inputs
Estimate the packed weight and dimensions for each jacket. Keep the destination and shipping service the same where available. Once you have measurements from the warehouse, update the quote. Include the item, domestic delivery, selected services, international shipping and any charges due at import or delivery.
Build a budget for your US ZIP code
Convert each quote to USD using the same exchange rate and date. Check whether the carrier serves your ZIP code and what the quote covers. Use the U.S. Harmonized Tariff Schedule to look up the item’s classification and duty rate, and ask the carrier which clearance or delivery charges it may collect.
