How to Source Air Bar Nex 4: Sample Order Workflow
Published 2026 · VapeWholesaleHub trade desk

A disciplined sample workflow shortens the path from first interest to a Nex 4 purchase order.
Distributors reviewing their Nex 4 range usually find that sample order workflow explains most of the variance in results between accounts.
Keeping a short internal note on sample order workflow for each SKU pays for itself the first time a dispute arises over the Nex 4.
Why sample order workflow matters on the Nex 4
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.
Evaluate across at least two weeks of real use.
