TastyVapor.us is the site
www.tasyvapor.us Geoff is Amazing. His flavors are Spot on, Awesome Prices, He's available via Skype and always willing to answer questions, His juice comes in high concentrations as well and he sells flavor doublers too. All around a great experience and now the only juice supplier I COMPLETELY trust. I have tried many and found Tastyvapor.us to be a winner. (*Note its not tastyvapor.com like I hadthought too, that previous poster is referring to tastyvapor.us)
Anyhow that's my vote, oh also you can pick to mix up to three flavors in the same bottle as well and ask him to make some stronger/weaker. It's a one stop custom flavor shop and his prices are amazing as well, much more affordable than anyone else I've tried.
