Juicy Vapor has great choices of configurations for sample packs - different sizes, different numbers of bottles.
I find all of their choices overwhelming. Some juices have been a bit weak flavored. If you like tobacco and like liquor, the B52 is tobacco that tastes like a B52 (Baileys, Southern Comfort, Grand Marnier). Some think their chocolates are good. Original SIn was good though it tasted more like apple to me than Blackberry Mojito or whatever they said it was. Only thing I ever got from them that I plain did not like was chocolate covered orange rind but not because it was bad - because it was realistic.
And dang it I am making me want to buy more juices and I am trying not to.
BTW I think Gourmet Vapor sales ends tomorrow - use the code vapefest for 50% off. They do not have sales often but they are usually great sales. Try vanillarum - that's my fave so far there ( a customer creation, not mine). Juices there are a bit of a crapshoot since many are customer creations (so please mark any of your own Flavor Creator creations private until you try them - if one comes out good you can go back and make it public). Expect slow delivery - they get swamped during sales.
