I don't think buying juices initially is a waste. It's helped me (a) to get on the vaping train and (b) figure out what flavors I like and quite a few that I can't stand. That said, I'm reading up on DIY as that's a logical next step for me, I like to cook! It will take me awhile to venture into RBAs which can also save money. I'm tool challenged, a hammer in my hand is a danger to me rather than the nail.
