Questions we are asked about leak resistance

What is the minimum order for Vape Sourcing e-liquid?

Mixed cases start at 24 units, which is deliberately low enough for a single shop to test demand. The discount steps begin after that, and the tier table is available on request before you commit to anything.

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

Most retailers work to a target of 53 to 65 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 should Vape Sourcing e-liquid be stored to protect shelf life?

Cool, dark and sealed. Heat and direct sunlight degrade both nicotine and flavour well before the printed date, and a shop window is the worst place in the building to keep stock for any length of time.

Are there different versions of Vape Sourcing e-liquid for different markets?

Yes, and it matters. Strength ceilings, bottle sizes and notification requirements differ between markets, so the version supplied is matched to the destination at the point of order rather than afterwards.
