Why shipping weight changes the comparison
A weight figure beside an item may refer to the bare product, the packed parcel, or a volumetric calculation. Label it before comparing rows. A low item price may lose its advantage when the product is heavy, bulky, fragile, or packaged in a way that increases chargeable volume. Add weight to the sheet before shortlisting, even when the only available figure is clearly marked as an estimate.
Categories that are often heavier
Footwear, dense outerwear, structured bags, watches with packaging, and electronic items can be heavier or bulkier than a simple photo suggests. Boxes, protective packing, accessories, and batteries may change the final figure. These are comparison prompts, not universal category weights.
How to treat calculators and estimates
Record the input, unit, source, date, and whether the figure is item weight, packed weight, or volumetric weight. Compare calculators only when their assumptions match. If a spreadsheet row shows a number without a source or definition, label it “unconfirmed estimate.”
Why an estimate is not a guarantee
Packaging, measurement method, carrier rules, and the responsible third party can change the result. An estimate helps compare two rows; it does not promise a shipping price, route, timeline, customs outcome, delivery, or tracking event.
Why tracking and delivery support belong to the responsible third party
Once a transaction or shipment exists, the marketplace, agent, seller, carrier, or other service responsible for that step should provide its own records and support. This site does not access orders, packages, tracking systems, payment records, or delivery claims.
