In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Diamond 4.
Why sample order workflow matters on the Diamond 4
Request samples with the final specification, not an approximation.
Retail staff rarely ask about sample order workflow directly, but their questions almost always lead back to it.
