Published 2026 · VapeWholesaleHub trade desk
A disciplined sample workflow shortens the path from first interest to a Diamond 3 purchase order.
What follows is a practical view of sample order workflow for the Diamond 3, written for people who place repeat orders rather than one off buys.
The most common mistake is optimising for the first order instead of the fourth, which is where Diamond 3 economics actually settle.
Why sample order workflow matters on the Diamond 3
Request samples with the final specification, not an approximation.
Where two suppliers look identical on price, sample order workflow is usually the variable that separates them over a full year.
