Orlando, FL here. Bunch of shops all over the place and I got a few favorites. Only E Cigz on E Colonial near Dean Rd has really good house juice, fresh made, and while not as inexpensive as online vendors I can grab my current ADV (Medevil, kind of a vanilla cakey juice) at $30-35 for 4oz. They also sell gear that's decently priced, but obviously cheaper online, but not too bad. Also a small lounge, nice people and all though the owner is knowledgeable about the vape gear, IMO not so much about batteries and safety. Not horrible at it, but I feel I've gained more knowledge than he has, by reading here on ECF (Thanks everyone!).
Orlando Vape and Ecig somewhere near Disney, can't remember exactly but easy to find online by their name. I really really like this store, nice big lounge, super friendly and have a huge selection of juice that I haven't seen anywhere else. Would probably have to look at different online stores to find it all, but it's the "Premium" juice mostly, so you get 20-30 ml for $15-22 depending on the juice. Got hooked on Tortoise Blood by Shijin after I tried it there and found out they carry the 100ml bottles too. I think all their gear is authentic, didn't really look much but I think their prices weren't bad from hearing the guy talk to someone about a mod. Big lounge here too.
Mountain Oak Vapor in Oviedo. Great store, great prices. Grabbed a Tobeco Airek for $15. Their juices are good and I think I paid only like $15 for a 30ml of high VG juice. Also picked up some drip tips and a chuff cap that were maybe 1 or 2 dollars more than what I would see online. I also went later and picked up a Coil Master for $10. Nice store, great prices and nice employees. Also a nice lounge.
I'll give an honorable mention to Vapor Safari too, in Maitland. They have a nice selection of premium juices, price for these is the usual. For gear, they only sell authentics so some are expensive, but I got my Mutation Xv4 there for $35 like a couple of days after it came out and I read about it. They also have a pretty big and nice lounge.
