Choose a category and compare several actual listings. Record the item link, seller, variant, size chart and displayed price; a low price alone does not show whether the listing is suitable. For shoes, compare foot measurements with the listing chart. For clothing, compare garment measurements with an item that fits you.
Check the available photos and listing details before proceeding. After an item arrives at the warehouse, compare its QC photographs with the selected option. Product prices and availability can change, and photos do not authenticate a branded item.
