How do I compare the landed cost of two sofa offers?

A four-step working method

1. Request package dimensions, unit weight and an itemized quote rather than relying on a lifestyle photo.
2. Normalize quantities and currency; enter freight, duty and local handling separately.
3. Confirm delivery access and assembly requirements using actual site measurements.
4. Compare after-sales terms, documented specifications and unknowns before deciding.

Common errors to avoid

• Comparing unit prices while leaving freight scope and package size unknown.
• Treating an empty worksheet field as a confirmed zero or a verified fact. Mark missing information explicitly.
• Sharing a working brief as a professional conclusion. Keep assumptions and unanswered questions attached.
