Here is a link for a Sigelei mini for 38.99 shipped from the US. They only have black but this is the cheapest I have seen it. I just purchased one as a back up to my mini. Not sure how many they have in stock but they are in stock right now. I have purchased from 101 vape a few times and never had any problems. Always ship fast.
