I'm currently using The Lost Fog by Cosmic Fog, Baie crème, and Streek. I've had them before and they were awesome. The first time I bought it, it was $21.00 for a 30ml I tried another site and they were selling it for $16.50, this last go around I noticed I was losing flavor I was only getting like two or three 5ml tanks of really good juice, and now all but a little flavor is left what's going on here?
