What to do first
Pick the article that matches the point where you are stuck. If the list is too long, use the shortlist workflow. If the photos feel convincing but incomplete, read the QC guide. If a link has changed, follow the source-link checks before comparing the item.
Practical guides for the next decision
Each article is built around a task you can complete. None of them can verify a seller, product, order, or shipping outcome, but they can help you notice missing evidence before a weak option reaches your final shortlist.

A product can come from a shared sheet, a marketplace listing, a storefront, or an image album. The useful question stays the same: what detail do you still need before this item deserves another step?
