Compare complete offers, not just the shipping line

Steps
1. Write the exact pair, condition, EU size and destination country on both records. If those differ, explain the difference before comparing totals. Keep a seller reference and the quote’s validity date.
2. Separate item price, shipping and any mandatory handling charge. Ask whether tax is already included and who pays import charges. Do not add a stated tax twice, or enter zero for a charge that is unknown.
3. Reconcile the fictional example: A is USD 300 + 25 shipping = 325. B is USD 300 + 20 shipping + 15 handling = 335. The cheaper shipping line produces the higher quoted total.
4. Before accepting, confirm the total payable to the seller and any costs collected separately, plus dispatch, delivery and return terms. If destination charges remain unknown, mark the delivered total incomplete rather than choosing a winner from a partial sum.

Worked record
Example A · invented: ____________________
Example B · invented: ____________________
Example-only tax assumption: ____________________
Comparison: ____________________
Unresolved destination costs: ____________________
Acceptance record: ____________________

Example A · invented: Item 300 + shipping 25 + handling 0 = USD 325
Example B · invented: Item 300 + shipping 20 + handling 15 = USD 335
Example-only tax assumption: The listed amounts include any seller-collected tax; no tax rate or real destination is asserted.
Comparison: B has shipping USD 5 lower, but quoted total USD 10 higher.
Unresolved destination costs: If import or carrier collection is unknown, neither sum establishes a final landed cost.
Acceptance record: Exact pair/size, country, currency, included charges, separately payable costs, validity and return terms.

The public item price and available sizes do not determine a destination’s tax treatment or carrier charges. Request a complete offer for your own destination and keep it with the enquiry. This worksheet neither opens a wallet nor issues an invoice, and it does not change the published delivery or return policy.
