Update! I found two more vape shops near me. Very near me - both are within 5 miles of my house. I had no idea they were there. I was searching for smoke shops when I should've been searching for vapor shops.
One of the stores is terrible. I've been vaping for a few weeks and I knew more than the two guys behind the counter. None of the juice was on display, and they didn't even have a binder listing the suppliers and their flavors. Also: $40 for one cheap-looking eGo battery.
The other is awesome, though. The owner was behind the counter, he gave me a 510-to-808 adapter for free and helped me pick out a good not-very-sweet tobacco flavor out of the several hundred flavors from over 10 different ejuice suppliers he had available.
Good choice, too. I love it, and it was about $7 for 10ml. I will definitely be going back.
So if you're in South Jersey, I can highly recommend
Vortex Vapors on the White Horse Pike in Galloway. The post office for some reason says it's in Egg Harbor City, but it's right by Pomona Ave. The USPS doesn't handle Jersey's townships very well. They think I'm in Absecon, which is miles away.
Vortex also has a loyalty program - $20 credit for every $200 spent.
(For the record, I'm not getting anything for recommending them.)
