Hey, I just want to provide an update: I went to Mr. Smoke on Lincoln Ave. earlier and picked up some juice (strawberry). I also bought some cartmoziers -- they're the bigger, cigar-sized ones, but fit my Magma battery just fine. Everything was way overpriced ($25 for 30 ml) but well worth it if you need something immediately. The guy working there was also very knowledgable and showed me the eGo-T. I am so going to move to a tank system eventually...but will just stick to my Magma for now. Hope this helps any Chicagoans fiending for some liquid.
Also, V4L is located in Winnetka, a suburb on the Northwest side, but, as far as I can tell, does not have a physical store that you can visit. Plus, I live close to the loop and have no desire to haul myself out to the burbs.
