the butter flavor both scares and arouses me...
It's in the first recipe that I have decided I want to try and mix, I was surprised when I first saw it too haha
Making this but a Strawberry and Raspberry version

Good to see another UK mixer here!
Good selection of concentrates there to get you started (I'm currently vaping a DIY Strawberry Cheesecake so might be biased!)
I've used JV247 a few times and haven't had any issues, some of their Kandi-Hed range is pretty good. I did find that postage got expensive for PG and VG though. You look like you're set for a while but have a look at classikool.com (UK site) for these when you need more - postage is much cheaper. I haven't tried their Nic or flavourings yet so can't vouch for those.
Another supplier to have a look at is chefsvapour.co.uk - they have a huge range of concentrates from loads of different brands.
I thought the postage was pretty reasonable for all that this time £3.95 for everything there. I ordered my nic from Alchemists Cupboard and their postage was super high.
Me and a mate in work are both getting into mixing at the moment and he found chefsvapour the day after I put my order in, I wish we had come across it sooner because their selection and prices seem to be the best so far, 100ml 72mg nic for £15, where I paid £12 for 50ml from AC
£3.95 is quite good! Last time I tried to order VG from JV247 It made shipping much more expensive, I think they even said something on the site about it being expensive to post and that it might be an idea to try and get it locally... This was quite a while ago though, I guess they've found a cheaper courier.
I've used PG and VG based Nic from Chefs Vapour and Alchemists Cupboard, I haven't done any proper tests on either but taste wise they're both fine - no noticeable pepperiness (is that a word?!) from any of them, all were 72mg diluted to 6mg.
I just posted a comment over on /r/ecr_eu with a few other links that might be useful (on mobile so sorry if it's a bad link):
