Want to try:
Alien Visions
Backwoods Brews
Heather's Heavenly Vapes
Have tried:
The Vapor Room--good customizing options, fast and friendly service, generally quite good juice. Often the flavors are not that strong, though, so I usually get an extra flavor shot. Also, their website lacks good descriptions for the flavors. I emailed them that suggestion and I got a nice email back, saying that they were going to include that when they upgrade their website (soon it sounds like?). I really like that they are so responsive.
Nettmix--this was the worst juice ever. I ordered probably 15 different samplers, and not one of them was vapeable, even after a month of steeping. They all tasted like plastic. Fortunately, it was a cheap mistake. On the plus side, I like the equipment I bought there!
RAWR--I really like most of the things I've gotten from Rawr, only a few "misses" for me. I love, love, love Truth Serum a lot, although it took a week or more for the best flavor to come out. I got a sample of the Proper Green Tea, and it was pretty much the best thing I have ever tasted, but I reordered a 55ml bottle and it's been steeping for almost a month and it still isn't all that it should be. The shipping and service has been great. I like that they email a tracking number so I can stalk the mailman!
Quick Nic--again, no problems with service. Juice quality seems good. I like the Watermelon Rancher, and my husband loves the Rootbeer Float.
My Freedom Smokes--the only thing I have tried from here is Watermelon Frost. Yum!
Otherwise, I have a bunch of ECBlend samples steeping, and they smell amazing! And I have some lemonade coming from Discount Vapers.
Sorry for writing a novel...
edit--Oh, yeah...almost forgot Tasty Vapor. Went to a Vape Meet there in September, and they were the best hosts you could imagine. They gave out some free samples, and the next time I am in Oakland, I will DEFINITELY be picking up some more Lemon Pound Cake!
