Hi there Emmer!
Have you tried the Do More Eh juice, yet? You mentioned you want to buy a big quantity, but I would only do that if you've tried it and liked it.
Most tobacco juices don't taste anything like a cigarette, but most people new to e-cigs are looking to mimic the flavour of their cigarette exactly. Many people are disappointed when they buy all tobacco juices to start and find they don't like any of them. A lot of people that think they're going to be tobacco juice vapers actually find that they like the fruit flavours better, or dessert flavours, or menthol, even if they hated menthol cigarettes or would have never thought they'd like vaping something that tasted like peach, stawberry, or blueberry muffin! lol.
Taste is very subjective when it comes to ejuice. What one person will love, another will be absolutely disgusted with. I would recommend that if you're just starting out, buy a bunch of sample-sized bottles of juices in various flavours. If you're buying from Canadian vendors, shipping is quick (a couple of days) so if you really like a juice, reorder it in a larger size. If you order a good variety of flavours there will always be a couple you'd like enough to tide you over to your next order.
If you've already tried the Do More Eh juice and love it, then totally disregard this post! lol. But if you haven't, I'm just trying to pass along some info so that you can learn from MY mistakes. lol.
If you go to the Canada forum you can ask that someone pm you a list of Canadian vendors of hardware and ejuice. There are a lot of really good Canadian vendors that have great customer service!
Cheers!
