@Highwayman Did you get round to making your own juices?
It costs me less than £10 (including all materials) to make 100 ml, using FlavourArt UK 10 ml concentrates and FlavourArt UK nicotine. It is possible to bring the cost down further by buying larger bottles when you know which flavours you will use more of, and/or cheaper nicotine. I use FlavourArt because of their reputation for quality and safety.
For anyone interested in getting into DIY, FlavourArt concentrates are mostly excellent but it is important to note that they are more concentrated than those offered by other companies, so they need to be mixed at much lower percentages. For example, the total flavour percentage in my most used mix is 7.4% and that would generally be considered a high percentage for FlavourArt, unless you enjoy really in-your-face flavouring.
There is an extensive (and highly recommended) 3-year old
thread here that contains a wealth of information about DIY mixing using FlavourArt products, including many different recipes:
