My favorites so far are
Backwoods Brew (esp Casablanca and Peach)
FreedomSmokeUSA (when not having a special sale their discount code is freedomsmokeusa for 10% off)
- lots of tobaccos to try
- tons of other flavors
- configurable PG/VG on the normal (not sampler) sizes of most flavors
Velvet Vapors (but they will be closed for about a month due to a family emergency)
I love their Vanilla Almond Tobacco (which is like a 555 but theirs is very smooth and sweet and not overly nutty) and their Raspberry Ginger Ale and Ginger Ale have a fun tingly TH and taste like their names - their Velvet Blend PG/VG base is nice.
Gourmet Vapor, mainly for the Flavor Creator which is crazy fun. I made a couple of duds and didn't make them public. But I like the Morgans Eggnog I made (eggnog w/ vanilla and rum like Captain Morgans spiced rum plus nutmeg). And sometimes they have crazy sales - I think today might be last day (or next to last?) of their 60% off sale on flavored juices? code VapeTV60
I have already been there twice during the sale. I hopefully fixed my duds and ordered them, and I made a Spiced Rum Peach and some flavored tobacco blends and if any come out good I'll make them public. BTW - when you are looking at the normal ejuices, searching for an ingredient works best and use the Search button (don't hit enter or the search won't work). So like search for Rum, or Raspberry, or Tobacco (for tobaccos that have tobacco in their name), or a tobacco type like Virginia or Latakia, etc. If you want to see a list of all the possible flavor names, go into the flavor creator (requires login)
