First of all, I've sampled Bob and Missy's
KBV and they make absolutely delicious juice! Yum!
For hardware, I have used all of these vendors and am totally pleased with them,
BreezeSmokes. Don is wonderful and very generous. I purchased some 901 batteries from him at clearance and he sent me a free charger. Don is also accommodating. I wanted to try out a VGO battery, and he found one that he had just tested and sold it to me for an unbelievably reasonable price. He also holds cool contests.
Liberty-Flights, for great discounted hardware, excellent warranties and speedy inexpensive delivery! It's also cool that if you review what you purchased, they give you a $.49 credit. So it's like 50 cents off on anything you buy from them.
GoodProphets for inexpensive adapters and just tried their 510 cartos, which so far rock!
Totally-Wicked has great customer service and with a good warranty on their products. One of the 1000mah auto eGo batteries I got during the yoyo sale died on me, and they just sent out a new one without asking for the old dead one back. Also, during the yoyo sale, I had 3 orders in 2 days, and they shipped them together, refunding my overpayment in shipping fees for 2 of the orders.
Honorable Mentions:
MyFreedomSmoke, also great customer service. I had ordered large eGo attys and carts from them and they ran out of the attys, so sent me eGo cartos to hold me over until the attys came in. I was also updated by email and phone as to the progress.
MadVapes for little fill-ins, speedy shipping
