I’ve had similar problems finding authentic gear and liquids for a decent price. Most of my friends who vape just stick to local resellers since international shipping is always a pain, and customs sometimes block liquid shipments so it’s risky. For coils, tanks, and even mods, I’ve often seen better options abroad but unless you know a supplier or have someone abroad, it’s hit or miss with delivery and authenticity. I recently checked out the new Uwell Viscore 8000 and was surprised by how many legit retailers carry it with good reviews about both flavor and battery life. It's worth looking into for anyone frustrated with lack of options and quality imports.
