How to use a spreadsheet without wasting an evening
Start with the category that matches what you want, then open three to five listings that look close. Do not decide from one image. Check the name, options, size chart, seller notes, and whether the listing gives enough detail for the agent to buy the correct item.
If a listing has weak photos, unclear sizing, vague options, or a price that makes no sense against similar items, leave it and keep moving. The best links reduce uncertainty before you order.
