Keep the seller's answer with the relevant product information. Ask for concrete information instead of a broad assurance that everything is suitable.
Avoid treating a high review count as a product specification. Consider whether an option meets your minimum requirements at all.
Confirm whether the total or any charges would change. Ask whether one unavailable component could affect the others.
