Buying from Parts Connexion

I'm based in the UK and very interested in buying valve tubes from Parts Connexion in Canada, anyone in the UK had any experience with this ? Thanks 
Why not buy from The Tube Store also in Canada and they carry every kind of tube imaginable?
I'm interested in the Takatsuki 300b tubes and it's the import tax and other taxes that i may have to pay that I need advice on.
You will pay tax in the UK on imports. There will possibly be a delay in delivery time. I have sent items to the UK from the US for repair and they got held in UK customs where I was charged VAT and a fee for processing!
PARTS CONNEXION and their sister retail outfit AUDIO CONNEXION are located about 12 miles down the highway from me. I’be bought numerous items from both.

Top shelf outfits - highly recommended and buy with confidence .
I bought a usb cable from them, which was shipped to the US.  The bad news-there was an error on their web site which misidentified  the kind of usb cable.  They shipped the wrong one and didn’t actually  have the one I wanted .  The good news-They were pretty good about acknowledging their mistake, sending a return label and refunding my money.  Honest mistake which can happen anywhere.  I would give them a positive rating.
Just buy from Brent Jesse Audio which have the largest selection 
of Tubes NOS.
Does Brent Jesse Audio actually sell the current  production Japanese Takatsuki 300b ? This is what the OP specified. 
I’m in Western Canada and have purchased from P.C. on several occasions. From components to cables, and have never had an issue, Chris and his staff are good people.

no uk sellers?
You know the saying if no prices are listed........
@jond  You are about to be ripped off with white-gloved hands.
I’ve purchased 2 pair of Takatsuki 300Bs from Parts Connexion with absolutely no complaints.  Quick service, great packing, friendly staff.  But, I’m in the States so cannot comment on tax/tariff to the UK.

Regarding the Takatsuki 300B, absolutely amazing tube.  Slightly tighter bottom compared with Western Electrics, wonderful mids and sparkling highs, very comparable to the WE.  Very thick glass envelope.

 I received a pair of new production Western Electric 300Bs with 2020 date codes from Rossville (Georgia) Works.  I’m just beginning to “age” them and so far am quite impressed.  

And, if you are ever in Japan, Kyoto in particular, go visit Takatsuki.  Appointments are made on their website.  They are very friendly and proud of their operation.  You can easily spend an afternoon in their listening room.  
man, what ad copy… I want, no need Definitive UK to write my obituary, just not soon…

” perhaps it’s the graphene, who knows ?
love it…
Definitive Audio UK are £2000 ,roughly $2760 usd , for the current Takatsuki 300b tubes......
...carved on the stone I don't want:

"If I have to roll Anything....papers 'n herb, puleze."

Good luck and happy shoppin', ya'll. ;)
Parts Connexion has really upped their game by offering more items than ever at decent prices.

The one caveat I have with PC is they do not have a refund policy. You can only get something of equal value or another of the same item purchased.

This was a hard learned lesson for me. I will only deal with sellers that have return/refund policies such as, Brent Jessee. Choose wisely.
Definitive Audio UK are £2000 ,roughly $2760 usd
$1600 a pair in PartsConnexion. Sounds like it might be worth the 23% VAT and fees to import. You might call PC to see if they'll double box them.
I bought Cardas cables from them twice. No issues. Fast UPS shipping but I live in US. 
In the UK,  Living Voice, Takatsuki, Western Electric | 300B Valves | Definitive Audio

International purchase and shipping can be a PITA. Doubly so since C-19 insanity.

Parts Connexion are first class vendors.
I bought a new Furutech E-TP80 power conditioner from them.  I thought it was a special sale for $766.00 USD, but after I purchased it, I realized it was full retail.  I like the Furutech and use it in my office system,   I believe it arrived in 3-4 business days via UPS.  It's my fault for not checking around on price before I bought it.  Shame on me!
Been buying a variety of components for years: with never an issues. If you have a problem Stephanie will politely and promptly sort it for you. They have a definite customer focus.
Parts/Audio Connexion are real and honest places to purchase Hi Fi components. I have purchased many items (tubes, gauges, wire, TT for my son, IC's, capacitors etc..) there, both on-line and in person. The staff is knowledgeable, friendly and honest, The retail store is well laid out and very "laid back".
If they sell what you need and it is at "the right price".... well... the rest is up to you. I know what I would do if I were you.
I live in Taiwan, and have bought several times from Parts/Audio connexion. They are great to deal with and offer very good service. I would recommend them to anyone based o my positive experience.

It looks like no one from the UK has responded directly to you with regards to experiences with buying from Parts Connexion in Canada. From what I read so far, I get flashbacks of when someone whispers (messenger game) something into someone else’s ear and passes the whispered message to 10 more people, and the last person ends up saying something totally irrelevant or way off the mark, LOL. Not to say that some advice may not be helpful, but no one actually from the UK who has the experience you seek has ponied up a response. 

I suggest you call Parts Connexion direct and ask them how shipping charges and VaT may be applied to your particular situation. I lived in Europe 25 years and had to rely on direct communication with companies in USA or Canada when I was not able to ascertain others experiences trying to obtain products from North America and transport to Europe. When things arrived in the public mail or UPS, FEDEX, etc., I almost got slammed with some form of import or duty tax. Good luck. 
They are an honest company, I have bought from them via mail order. Their owner used to own Sonic Frontiers so they have a long history in the industry. Sonic Frontiers was a Class A rated tube equipment manufacturer so they know tubes. You are safe with them
Thanks everyone for your responses, AudioQuestforlife is spot on with your comment. I have full trust in Parts Connexion just the extra tax charges concern me ...
I am in the US but I can highly recommend them as being a class act.

Lost some parts in the mail and they promptly replaced them no questions asked.

Super responsive via e-mail.

Also the best source I know of for pure silver balanced interconnect cables for the DIYer. 

Sorry but bad experience with Parts Connexion.

Ordered a pair of XLO Reference 3 speaker cables. I received the cables with two differents versions of banana plugs. Not fakes ones but probably demo cables or cables for trade shows. They don't respond to my messages…

I bought some HiFiTuning fuses and there were no problems other than they are slow to ship items, at least in my experience.
