Hey! I'm in the same area as you! If you don't mind traveling around a little bit there are REALLY great vape shops around!!! I believe the ones I went to were mostly in OC area but there are some in Alhambra, Anaheim, Cerritos, and Garden Grove. Yelp "e-cigarette" and you'll get the list! Some of these shops are bare bones: one counter of very basic stuff and some testers... while others can get pretty elaborate. I believe one of the shops even has a pool table to play on. Vapor Loft has an iPad area to play around on...
Btw, I went to Vapor Spot and got a few liquids myself then realized you can buy the same liquids from the vendors directly if there's a flavor you really like and want to get a lot of.
Also, at the other vape shops they have liquids from other vendors. Btw, Vapor Spot carries liquids from EC Vapors, Virgin Vapors, Pink Spot, Halo, High Brow, etc...
I really liked Fuzion Vapor's Gumby Blood and Krankberry: both of which you can try out at Vapor Loft (Orange) or Pure Vapor (Walnut). Another favorite (several customers at other stores suggested. I've yet to go, but I'm checking it out this weekend) is Vapor Revolution (Cerritos). From what other vapors have told me, they're pretty packed all the time but you meet new people, get some good advice, and some really good testers.
Hope this helped some!
