I just did.Dan, just get it from Cloud9. VapeRev is the only US distributor that I know of and I don't expect they will have stock for quite a while as they just sold out yesterday.
Cloud9's site was all over the place showing that it was in stock then out of stock, then in stock again. It seemed as if it has sold out, but when I registered, I was able to add it to the shopping card. I paid via PayPal and it seems like I bought it and the order went through, I hope. I already bought one kayfun from flavourartexpress in Russia, but with so much positive feedback, I decided not to wait until I get it from Russia and get the second one. I figured, if it is not for me, I can easily sell it here, unless they come out with the new version that blows 3.1 ES out of the water.
