Just an update - I went to the Daytona Flea Market this past weekend and I saw a total of 5-6 e-cig vendors there... Most of them were tiny booths with limited stock/selection and many knock off/no name brands. The one found that I'd been looking specifically for was in one of the air conditioned buildings (E2 shops, I believe). They had a large selection of batteries, delivery devices, and juices to try. I personally gravitated to the Kanger section and noticed that the MT3s were priced at $10 whereas I can get one online for $6. They had protanks, too, but I didn't ask how much they wanted for them.
I noticed they carry the same Ego-C Twist that I have and the lettering on the battery looked a little different - I don't know how to describe it but the print looked odd. Not saying they're knockoffs, they just looked... off. Lots of selection to choose from, though. I don't have tons of experience with all the devices available, price, and whatnot so I can't say I recognized everything they had to offer there but I liked the place well enough to go back and see what goodies I can find. It was a rather large, bright booth.
The woman working there told me that their shop in Sanford near Walmart off 17-92 is open 7 days a week, so when I have more time to play, I may pay them a visit.
I know this was a little long winded, but I thought maybe it could help out a few local fellow vapers ;-)
