You yanks get all the best deals, it's not fair.
I use darkstarvapours for my bulk old reliables. They've great prices but a poor selection
I use chefsvapour (now chefsflavours) for some bulk and some smaller bits, they have a great selection (20% off right now) but so much stuff is sold out, they NEVER have full stock.
I use e-dym.pl for a crazy 10ml spree and they have great prices on FA stuff, but they don't do bulk.
Any hidden gems I'm missing?
vapable.com has a pretty good selection.
Since you are in the EU, it's a good bet to order from FlavourArt and Inawera themselves. For other flavours, I guess you already know how it goes.
You Americans who're reading this thread should know how lucky you are in terms of suppliers. I sometimes look at the American stores and get very jealous. Whenever I'm making an order here in the EU, there's never ONE store where I can get everything I need, there's always something missing. With some bulk orders I have to order from 4-5 different websites, the shipping costs certainly rack up.
Edit: Also OP, did you check out flawyer.de or vapourdepot.com?
Do you know whats holding back the American stores from shipping to the EU?
There are some stores that ship international in the US. I ordered from them a few times but found it wasn't worth the hassle. My packages often got stuck in customs for a week. So on top of the customs fee, you're paying for international shipping as well and the price ended up more expensive than ordering from within the EU.
I've ordered from The Chosen Few a few times when I couldn't find something specific locally.
I hope I formatted that link correctly.
the vendor list from /r/ecr_eu may turn up a few more places for you https://www.reddit.com/r/ecr_eu/comments/4ewsyj/ecr_eu_diy_vendor_list/#vendors
Other than Chef's I use https://vapourdepot.com/product-category/diy/concentrates/ for TFA and Flavorah, they do up to 30ml, 15% off with VP10 this weekend, also permanent reddit10 code, though Chef's can be a little cheaper and they also have some out-of-stock on larger bottles. They also have some interesting stuff like Botanic Elixir, Health Cabin, Lorain, Real Flavors.
FA I use www.flavourart.co.uk who have everything FA, no discount code but a multi-buy deal on 10mls and they do 100ml bulk.
http://www.rainbowvapes.co.uk/ have Capella and INW 100ml and http://thee-cigshop.co.uk/DIY have some bulk sizes too.
I've been having the same issue as op here so I went through some of these other sites recommended and the prices are very expensive in comparison. I've used the contact form to contact the guys over at chefs vapour to see if I can get an order placed and have it shipped as soon as it's ready as the stock on the website comes in and out so frequently it's difficult to keep up.
I will keep you posted and let you know how it goes if anyone's interested.
After some digging through the recommendations, nothing linked here is anywhere near as good as the three I linked in the OP. If chefsflavours had stock they would be perfect. Maybe if money people annoyed darkstar they'd star to stock more stuff, at least in 30ml bottles. They're so cheap their 30s are sometimes the same price as other site's 10mls
