I've found a few shops that carry a some e-cig juices - a couple on SE Division (one being Still Smokin) and one between Vancouver and Camas. Trust me - whatever you're paying in shipping is going to be a LOT less than anything the shops are selling and you'll have a better selection with the online venders. By purchasing some of my stuff local though, I'd like to think I'm creating more awareness and supporting local businesses... but honestly it's the procrastination-thing. The only reason I really buy from these shops is due to my procrastination and suddenly realizing I'm going to be dry before an order arrives.
I've found that the smokeshop going-rate for e-juice is right around $1/mL - so doing the math, it almost always comes out cheaper ordering online - even with shipping (unless you pay extra to overnight it).
Madvapes 5x10mL sampler pack using cheapest shipping: $17.98
Local shop's 20mL (tried most, they all taste "off" to me): $19.95
EDIT: Almost forgot the local mall kiosk's prices...
Mall Kiosk 3mL: $14.95
Yeah, I prefer online, but hate waiting, lol
