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

Ask whether the requested action is possible within the standard process. Confirm whether accepting an alternative changes the total or timing.

What should I check if my checkout session expires?

Review the existing order history through the seller's documented channel. Use the seller's normal checkout route rather than an unfamiliar recovery link.

What should I check about requirements or limitations before purchasing?

Check whether examples describe the same circumstances as your planned use. Check whether access or availability is subject to conditions relevant to your order.
