How can I compare prices when offers use different purchase units?
Keep the currency consistent across the compared amounts. Compare what each purchase actually provides for your intended purpose.
How can I find out whether a special request can be accommodated?
Ask about feasibility before submitting an order that depends on the change. Do not treat a general willingness to help as acceptance of a particular specification.
What should I clarify when I need a purchase by a particular date?
Look for separate timing attached to optional additions or customization. Ask about an unclear status before submitting a time-sensitive order.
