Questions we are asked about refilling and maintenance

How do I check that a batch of Vape Sourcing e-liquid is genuine?

Every retail unit carries a scratch code that can be checked against the production record. A code that fails twice, packaging with inconsistent print, or a price well below the normal floor are the three signals that should stop a purchase.

What is the realistic wholesale margin on Vape Sourcing e-liquid?

Most retailers work to a target of 29 to 43 percent at the counter, with the figure moving up when accessories are bundled. Margin per shelf metre is the better measure, because a fast-moving line earns more than a high-margin one that sits still.

What strength should a retailer stock first for Vape Sourcing e-liquid?

Start with the middle strength in the range and add one step either side once you see what sells. Shops that open with a single strength almost always have to reorder within a fortnight, and the second order is usually the one that reveals the real demand curve.

What causes a burnt taste with Vape Sourcing e-liquid?

Nine times out of ten it is priming. A coil that has not been saturated before first use, or a tank run dry, will scorch the wicking and that taste does not go away. Fitting a new coil and waiting a few minutes before the first draw prevents it entirely.
