Extracts

[Indianhippydude]

Hello people. Hope you're all bless.
Quick one. I heard that vapes still really aren't a thing in Dam, unless you're lucky and have deep pockets.
I'm flying from UK so planning to take a few empty ccells with me as really wanna vape on the go. Where would be the best place to buy extracts in terms of price vs. quality to fill these up? I'll be filling them half way as I hate overusing the coils so maybe a 0.3 or so in each one. Would I be better off buying 1g of one thing?
Thanks in advance from someone who has always smoked flower.
