How can I ask for product information in a format I can use?
Tell the seller which alternative format would help you understand it. Do not treat the absence of an alternative format as confirmation of a product feature.
How should I interpret a seller's deadline when the time zone is unclear?
Ask which time zone applies to the stated deadline. Check whether the date includes a specific cutoff time.
How can I decide whether an optional addition is useful?
Do not assume an optional benefit continues indefinitely without stated terms. Ask how a change to the main order would affect the addition.
