The big tobacco owned products like Vype are almost always seen in petrol stations, off-licences and small shops that sell, or formerly sold tobacco and cigarettes in addition to their main business. Prices for liquids are 3-4x the price of the vape shops. You still sometimes see these places selling the silly, tiny e-cigarettes that look identical to a king size smoke, with LED where the tobacco used to burn. You won't ever see these anywhere else. I've seen exactly one person using one of these compared to hundreds using regular vape pens and box mods.
Juul was late to the UK party, and I've yet to notice anyone using one of those, though I have seen one or two garages with a few packs of cartridge refills, but they don't seem common.
