Gr8 Vapes has two locations in Texas, one in San Marcos and one in West Bastrop.
The San Marcos shop because my favorite while I was staying in San Marcos. They mix their juices in house, in front of you, while you wait.
Their VanHazel Nut and Vanilla Custard flavors were all I smoked and still remain two of my favorite flavors. Unfortunately, it looks like their online shop doesn't sell either of them.
The staff are knowledgeable and can help you with just about anything you need. There is one exception, coils. I use the Kanger 2.2 ohm coils in my Pro Tank mini. I asked for these coils in the shop and the girl behind the counter said that they had a generic coil that worked the same but was a little less expensive. I opted to give them a go - they were horrible. They tasted like burned plastic and just didn't go very well with my Spinner variable voltage battery. On my next trip in I again asked for the Kanger coils and the girl behind the counter assured me that what she was giving me but they were once again the cheaper ones, only this time she charged me more. I was not a happy camper.
Gr8 Vapes also has a rewards program through Five Stars which allows you a free 10ml bottle of juice for every 100 points. They also give you a free 10ml bottle of juice for your birthday which is pretty cool.
Overall, I would say Gr8 Vapes is a wonderful place to get your e-juice but not so much for equipment unless you just need a battery. Stay away from the generic coils and don't expect to be able to get true Kanger coils there.
