How can I make a useful comparison table for several products?
Use the same comparison criteria for every option. Use the table to support judgment rather than replace it.

How should I interpret a seller's deadline when the time zone is unclear?
Keep the original date and time alongside any converted version. Use a reliable time converter when comparing different locations.
