I'm finding that things are gradually getting cheaper due to more small mom and pop shops popping up here and there. Which is of course good to see.
For example
KVAPE is selling the nuatilus mini for KRW 25,000. still a little more expensive than fasttech but worth the faster shipping imo.
To the OP, If you're saying you want to get the justfog, you can buy them from their official website
here. But looking at the product and the price they go for, I'm sure there are better options out there.
