Heh. “Reasons” like people take them away from you likely.
Yes they exist. They generally don’t have a terribly good vape and are(of course) made in China, so they tend to have Chinese flavor profile juice which also tends to be older since it spent a lot of time in a shipping container. You can generally get them at any US gas station or order them from the manufacturer for usually around 1/3rd the price. Takes longer though and generally includes some shipping fee.
