There's a store in Oakland called The Vapor Room. I don't have the address but you can Google it. I've been meaning to go by and check it out but haven't got around to it. I live a little furthet than you from Oakland, I'm in the Fairfield/Vacaville area. If you do go try to post your impressions of the store, I'd like to know how it is. Good luck.
vaporden - An Electronic Cigarette Emporium
This place is in Berkeley. I think they announced their opening on ECF about 2 months ago. Give them a call and make sure they are still open.
it's $1.00 per mg I bought 10 grape and 10 "desertshield" it's their version of the Ry4, honestly bro I liked my Xhale02 better imma go to 7-11 and get some re-fills, UNLESS the reason it tastes like .... is still the primer plus it is so harsh on the throat, Imma keep vaping and hopefully it starts to taste better. Have you visited the website yet and became member for free? he'll keep you informed of any meetups in the area, He says he has alot of turnover so his juice is always fresh, his spot is clean so I def wann go back.
