How to Source Air Bar Diamond 2: Sample Order Workflow
Published 2026 · VapeWholesaleHub trade desk
A disciplined sample workflow shortens the path from first interest to a Diamond 2 purchase order.
Buyers who treat sample order workflow as a commercial discipline rather than an afterthought tend to hold margin for longer.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Diamond 2.
Why sample order workflow matters on the Diamond 2
Request samples with the final specification, not an approximation.
The most common mistake is optimising for the first order instead of the fourth, which is where Diamond 2 economics actually settle.
Evaluate across at least two weeks of real use.

Practical notes for buyers
Where two suppliers look identical on price, sample order workflow is usually the variable that separates them over a full year.
Cash flow is the quiet constraint behind sample order workflow: the cheapest option is rarely the one that frees the most working capital.

Commercial terms
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.
Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.
