I would recommend ECBlends, site with tons of flavors and good prices... they definitely have some good juices, but overall, most would consider them below average/meh. But I wouldn't rule them out, you might find some gems in there if you try enough juices.
Purevapes also has 15ml bottles for $8 (as pricer vendors charge $5-6 for a 6ml for reference). I got a sampler pack from them and was very impressed with most of their juices and definitely vapeable right off the bat!
I'd personally try to get sampler packs from more popular vendors that offer them and look for vendors that sell the types of juices you like (Bakery, tobacco, fruit, etc). I'm a juice snob though, seems like after hundreds of flavors and dozens of vendors, I still haven't found that "all day vape". I'm starting to feel like I may not have one... I just like to switch flavors constantly and can't see myself vaping anything all day. But that's ok. Just more money for me to spend!
