Start with a useful row
Keep the original listing URL, product type, exact variant and your own questions together. Add the date you checked it. A spreadsheet should help you compare items rather than hide uncertainty behind a long list of links.
Separate references from evidence
An image or saved price is a reference, not proof of current availability or the item you will receive. Record measurements and source details from the current page. Mark incomplete information so it does not get mistaken for a confirmed specification.
Move from discovery to a shortlist
Choose a few relevant items and compare the same fields. The search box opens RyFinds; read each destination page and the relevant service terms before making a decision.
