You've got the Kandi-Hed from justvape247?
Look at the resource page for EU vendors, there are some discount codes too.
I like www.chefsflavours.co.uk, they have good prices. Code POTV gets you a discount, I think it is 5%.
As a fellow European I wouldn't recommend ordering from the US, the shipping fees are atrocious, delivery is about as slow as the slow boat from China and when you're very unlucky, you get custom fees as well
DarkStar Vapour sells quality nicotine and flavorings. For 12% off flavourings and non-nicotine products use code: ELRECIPES
https://www.liberty-flights.co.uk code ORDO for 10% off

Oh, before I forget, welcome to the forum
