Give each item a reason
Record why it belongs in your shortlist, which option you need and the maximum total you are comfortable with. Remove duplicates that serve the same purpose unless you have a clear reason to compare them.
Resolve measurements and variants
Use a garment or object you already own as a measurement reference. Record the selected size and colour in one place. If the purchasing service provides warehouse photos, compare them with the recorded option and raise mismatches through its support channel.
Review the complete estimate
Ask the relevant service for current shipping estimates, service charges and packing information. A product price alone does not describe the cost of a parcel. Confirm the final amount and terms at the destination.
