wow that sounds like great cusomter service and it's really cheap!!
Yeah, it is great customer service, and really cheap. And on top of that, they're juices are all great. As long as Vapor Renu is in business, I have no reason to even try anybody else. They are the first and only e-juice supplier I've tried. Everybody else seemed way too expensive to me.
Also, in addition to doubling my order for free, I was allowed to select two different flavors for the two free bottles if I wanted to, so I didn't have to get doubles of what I ordered. I could also try two other juices for free. Another thing that I think is really cool about Vapor Renu is that they will take suggestions. If you have an idea for a juice flavor they don't already have, you can just e-mail them and ask them to make it. They also give credit to whoever suggested the flavor.
The only bad part about them is their site was a bit confusing to me when I first looked at it. I was trying to figure out where the e-juice was. Most sites have it set up so that there's a different page for each flavor/size of juice, so there's a page for a 10ml bottle of menthol juice, then another for the 20ml bottle, and so on. Vapor Renu does not do this. They sell only 30ml bottles for about 7 bucks. There is ONE page for ordering the juice, and that one page contains all the options(PG/VG, flavor, throat hit, etc.). When you go to their site, make sure you click on "Exclusive Flavor Nu-Juice Liquid Refill." Apparently when my brother went to order he ordered just the flavors(they sell DIY supplies too) by accident. When he realized it, he e-mailed them and they fixed his order.
