Yeah, those look like "sample sizes" of e-liquid from what I've read. I think a pack-a-day guy like me is going to go more for the 18mg variety at around 10ml/day (that might be totally wrong, I'm just going from random internet sources) and the kit includes 2x6ml bottles, one 6mg and the other 12mg...
The problem I have is that I'm in Canada, so I don't really know where I should order my e-liquid from. I've found a couple of sites via google, but no one has actually vouched for them so I don't know if they're any good. I know it's not a problem to get devices shipped in from the US or wherever, but I think the e-liquids are a different story. I almost want to write to the gotvapes people and ask them if they can just leave the e-liquids out so that there are no border issues, but in the end I don't really think that the border people will really care enough to give me any trouble, but better safe than sorry I guess.
