Vape Central has a huge amount of eJuice selection, and all are available to try on sub-ohm tanks. You can't beat the selection. Mark has been especially helpful, and one of the most knowledgeable guys I've met when it comes to vaping. The store is clean, and the people there are always helpful and willing to spend time to get you whatever it is you need. Customer service is top notch!! Pricing is great as well. Overall this is my favorite vape shop in Arizona.
