I have ordered off them a bunch of times. Always speedy service and I think their prices are always mostly on par or cheaper than others. Really friendly staff if you need to contact them via email.

For larger bottles (50ml) they use these narrow rectangular ones which may be easier to fit through some folks letterbox - and I guess costs them less to post - which is nice.

First ever problem came with my most recent order. 
I received FW Toasted Almond, rather than FW Caramel Cinnamon Roll...and it was out of date! Then I realised that I hadn't even ordered the CCR, and that the TA was a freebie. 
I dumped it anyway, but nice to get something for nothing I suppose...reusable bottle > Haribo!

They are a good company shipping isnt bad it's got the most selection of any vendor I've seen before and almost always got promotions on, the last 3 times I've ordered I've gotten 10ml samples albeit a flavour I would never use, packaging was alright they were inside a zip lock bag inside a bubble wrapped envelope

my go-to vendor (I live in Finland). I complained about how I couldn't track my orders and they made it possible. Also nice how they included freebies with my orders.

Rainbow is my main goto supplier. Prices are better than average. Free shipping over £10 and I normally receive my order within 36 hrs. Customer service is very fast and any issues sorted out immediately. I normally receive something free in every order. The biggest selection of single flavour and one shots I've ever come across in one place. My goto one shots atm are OHW Rocket Girl, Yogi Blueberry Granola and Humbles offerings. 5/5 across the board.

Big fan of rainbowvapes. Competitive prices and fast delivery in the UK. You get flavour concentrate freebies depending on how much you spend. Great selection of flavour houses. Website and packaging is not as premium as chef’s but the big plus side for me is that you get free UK shipping over £10 orders compared to chef’s free shipping only over £35 orders. This makes rainbowvapes great for topping up your stash.

The freebies can be a bit hit and miss, got tomato once, too scared to try it. But another time got SA marshmallow which I would never have bought, but has completely replaced TPA marshmallow for me.

Found One shots and concentrates I don't see on any other UK sites. Highly rated them, Fast delivery and usually a free concentrate in the package.

Fantastic range of flavours in the UK. Good prices. I've used them several times, always prompt delivery, reasonably well packaged. You get a free flavour of something, which i never use, the last one, bubble gum I poured into some liquid soap. On a personal request, I would love you even more if you could stock all of the flavours for "the best recipes of 2018", as I cant find them anywhere in the uk.

My go-to vendor as well, couldn't be happier with their service. Cheap prices, good delivery price and speed (one of the fastest around), excellent friendly customer service. They always try to ensure the package fits through a letter box which makes it hassle free, and the packaging does not have any kind of brand name or advertising on it.

They seem open to feedback about what to stock, I enquired about LA a while ago and then a few months later they started stocking it.

Rainbow vapes are a very good company left feedback on google :)..Good prices and they sometimes have some good sales one great customer service,Nice selection all round good company from but i had a bottle leak theis was replaced straight away.. Check out there deals they have on some of there sales products or ear to the end of date can be around 3 months left on the one shots so a few weeks steep and you got yourself some cheap juice.
