Separate the item price from the total
A listing price may not include delivery, service fees or destination charges. Ask the service you intend to use for its current estimate and what that estimate includes.
Make a short comparison
Compare items with similar specifications. Record the selected variant, quantities, shipping assumptions and the date of each estimate so that differences are easier to understand.
Leave room for uncertainty
Shipping estimates and currency conversions can change. Avoid treating a saved spreadsheet number as a final quote; confirm the amount and applicable terms at the destination before ordering.
