There is. CigEasy might sell them (they're not listed on their site), but I'm certain that the same source Catmom mentioned earlier has them on hand. And I believe they're in stock too.
Once you try a Go-Cart I'd be surprised if you ever wanted to go back an 808 one. I did not - and ended selling a BUNCH of 808 blank carts (and batteries too).
thanks for the reply. I have a few G6's, but the carts im not too crazy about, or I'm becoming too picky. I need to make some kind of change because I'm not enjoying vaping as much as I did when i started. I don't want this to be taken as a slam against Halo, because it's a great product. For it's model type, it's preformed well and I would recommend it to anyone who wants to give these a try.
I decided to pull the trigger and order a gogo from cropduster's after seeing how many people loved the product on this thread. hopefully it gives me the same experience as those of you who swear by it.
