I had a chat with Jay Blazio and was informed that they are working on smaller bottle sizes and will soon be offering 15ml bottles in the next few weeks, and sample packs shortly after that. For those who are hesitant about the one bottle size they now sell , this should be good news. It is very good news for me because so far I really like what I've tried up to now and don't want to get stuck with a full 30ml bottle of something I don't really care too much for.
