In Los Angeles (proper) there's The Vapor Spot near UCLA. They have another location in Van Nuys (The Valley). The juice selection is pretty good. Mostly RAWR, EC Blends, Pink Spot, Highbrow, Halo, and a few others. Juice is sold at $1/ml. No discounts though they have been known to sell an unopened 30ml bottle for $25. Unfortunately the juice is the best deal you'll see in this place. Common hardware (batteries, cartos, attys, drip tips, etc.) are at a staggering markup, often upwards of 100% of online retail. The staff is very friendly but not very knowledgeable considering how much stuff they sell. The biggest plus about going there is that they welcome customers to sample as many flavors as they like using their own drip atty or they will provide a cheapo carto for a buck. A good way to try out flavors without ordering sample packs.
