Hi all ill start by saying I mix for myself,but at work I've got a few people liking my juice,how much do I charge say for 30 ml,what's fair.
How long is a piece of string? I would work out the costs of making the juice, including money towards syringes, bottles, delivery costs of ingredients etc, then whack on a bit extra! If mixing is a pain then add on enough to make it worth your while, if you enjoy it and/or you just mix for them when you're mixing anyway then just add on a little bit, help to cover the cost of some of your own juices!
Cheers all,£8for 30 ml sounds about fair,I will also throw in an 8 ml tester flavour,try to get a few people trying something different because I've done the same and found a few I'd otherwise missed.
