My DIY juice is less that $2 per 100 ml. It's super cheap and super easy to make. If you can mix a rum & coke, you can make juice.
MFS has a "starter kit" but there is a lot of crap in it you don't really need. There's a DIY sub-forum here with lots of great advice and recipes. Here's the advice I give to folks looking to start:
I mix up about 300 - 350 ml of juice every 2 weeks or so. It takes me about 2 hours and I make a dozen or so flavors. This is my entire set-up:
Tri Pour Beakers
100 ml x2(you can skip these until you nail down a couple of recipes you like enough to make in 100 ml batches)
Graduated Cylinder - Polypropylene - 50ml
50 ml x1 ; 10 ml x2
Syringe with 18ga Needle
3 ml x2 - and I bought some larger gauge luer lock tips to make handling VG based nic easier.
I have a couple dozen bottles from when I bought pre-made juices, and I bought a few 250 ml & 125 ml amber glass bottles to break down 1L bottles of nic for storage.
And some of these for the recipes that are nailed down and I make in 100 ml batches:
4oz Natural LDPE (Soft) Boston Round w/ Black Twist Top Cap
I have a few pipettes that came free with flavor orders, but I almost never use them. If I can use a whole ml of a flavor, the graduated cylinders work fine. If not, syringes.
I started off making 5 - 10 ml batches, but quickly found 2 recipes that I liked. I made a couple of 30 ml batches, then a 50 ml batch. Then I jumped to 100 ml in those 4oz bottles. When mixing, especially in larger batches, leave some headroom in the bottle. I mix 100 ml in those 4 oz (120 ml) bottles so there is room to shake them. If you fill a bottle all the way to the top, it's harder to get it mixed well. I use one syringe for nic, and the other for flavors that I need to measure in less than 1 ml increments.
Fruits steep faster and are more forgiving if you get the % wrong. Vanillas, tobaccos, bakery flavors need long steep times. Sometimes up to a month. When you get a new flavor, mix it up by itself the first time so you know how strong it is and what it tastes like. Take copious notes, even when you make something terrible. (This will happen!)
The best advice I can give you is to try not to over-complicate the process. Some folks want to make it into some kind of mad science experiment. Think of it more like bartending. A dash from this bottle... a few splashes from that one... pour it in the bottle, shake it, vape it. The only thing you can really do wrong is to put too much nic in it, so double check your math on that. When trying something new, make it 0 nic first. Nic is the most expensive component so don't waste it. Otherwise, have fun with it.
