Questions we are asked about leak resistance

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

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.

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

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 is the realistic wholesale margin on Vape Sourcing e-juice?

Most retailers work to a target of 55 to 72 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.

How long does a unit of Vape Sourcing e-juice last in normal use?

For a typical adult user the answer sits between 9 and 13 days, depending on draw length and power setting. Heavy users will be at the short end of that range, which is worth knowing when you plan reorder volumes.
