What should I know before adding special instructions to an order note?
Clarify which instruction applies if you sent a later correction. Do not rely on an unconfirmed note for a critical deadline.
How can I write useful feedback after a purchase?
Give concrete details instead of relying only on broad praise or criticism. Mention relevant limitations in your experience rather than claiming to represent every buyer.
What should I check if an offer requires a minimum purchase?
Avoid submitting extra orders while an eligibility question remains unresolved. Review any maximum limits as well as the minimum requirement.
