What should I clarify if I need to communicate with a seller in another language?

Ask a follow-up when the answer appears to address a different product detail. Do not interpret a brief polite reply as acceptance of an unstated condition.

How should I interpret words such as up to, from, or optional in an offer?

Ask whether your intended use needs an addition that the listing calls optional. Check whether a promotional illustration shows the basic or an enhanced option.

What should I know before adding special instructions to an order note?

Do not assume a note overrides the selected product option. Do not use notes to replace information required elsewhere in checkout.
