I've been DIY'ing more than a year and don't have that much flavors. When I started, I started with a couple flavors and a sweetener. I just thought I'd mention it so people that are new wont be scared to start DIY and think they have to make such a huge investment. Things I've learned: 1. Most of the flavors I've purchased have been used once or not at all yet. 2. Most flavors and recipes you make won't be what you really enjoy vaping. 3. Eventually you will find 2 or 3 recipes you really like alot and that's all you will want to buy later. 4. I have come to love the alcohol based flavorings and they aren't perfumery unless I use too much. 5. All flavorings will be perfumy if you use too much despite what brand it is.
DIY can be alot of fun as well as a bit frustrating sometimes. Sometimes I had to step away for awhile and try it again at a later time and read more about it. Hoosier on here is a member and has a real good blog in his description about DIY that was very helpful.
