Why cant we get the same amount of choice from one site or even more choice from the existing ones?
Short answer: Money.
Longer answer: There is a bewilderingly large amount of 'stuff' connected to vaping. There are hundreds of flavours of e-liquids to start with and various strengths of e-liquid, To stock one flavour ideally you want a minimum of 100 bottles or so, more if the lead time is long.
There are regulated mods (vamo,SID,Smok ZMax,Sig Zmaxes, SVD) those are just mid range tube mod styles then you have pen styles, box mods, cheap mods, expensive mods.
Mech mods. You could write a list 100 entires long and just cover sigelei, there are a LOT of these, short ones, long ones, brass ones, SS ones, brushed ones, polished ones, pinky button mechs, bottom button mechs, cheap and cheerful mechs, mid priced mechs, high end mechs.
eGo batteries 650mah 900mah 1100mah VV eGos pass through eGos (and every eGo you buy in the UK can't be an 'official Joyetech' manufactured one because Totally Wicked have an exclusivity agreement so you have to buy clones (or buy from TW or find a n other way of getting hold of them, turns out SmokTech and Vision branded ones are equally as good fwiw) and those are all available in a multitude of colours and styles if say you want smoktech ones the minimum order quantity of those is 50pieces of 1 style/colour.
Atomisers? ignoring knock offs you have vivi novas, protanks, evods, iclears, carto tanks, CE4s, which you can get in differnet colours and sizes, there are hundreds of different variations on those from various manufacturers.
God knows how many drip tips are out there.
There are many sizes of battery all of which you can get in ICR, ICR protected, IMR.
So if you want to stock ALL of that you need a big chunk of money for stock. Then you need money to pay for the behind the scenes office work that ordering them, stocking them and doing the due diligence paperwork requires, the more stock you have the more forms and stuff you gotta write.
You need to have a customer service person who picks up the phone and answers queries who can give help and advice to customers about anything that you have in stock who uses(used) and believes in the products they are talking about. On top of all of that you need to keep up to date with the market and not have too much stock that you get saddled with 100 v1 LavaTubes which you can't sell now cos noone wants them but enough stock so you don't go out of stock in 2 days flat and have to re-order from China (2 weeks)
Then you have competition from several hundred other websites one of which will always have a sale on and will be selling below cost, one of which is selling off a job lot of cheap rubbish "I can buy an eGo kit from the market for a tenner, why does yours cost £45" so you also don't want to spend a lot of cash on stock that you might not be able to sell at a profit in a reasonable amount of time. Lets not talk about FastTech.
Oh and good luck getting funds from a bank to fund your e-cig venture now with all the MHRA bollocks. You can blag a couple of 'personal' credit cards or 'personal' loans perhaps but actual proper business finance for an industry that might be regulated out of existence in 2 years time ...
We added up all of stock here last week and were really surprised how much money we have tied up in it already and we have a small range of stuff on our site so far. To add all the things to our shop that I'd like to would be a crazy sum of money.
The main UK vendors are Liberty Flights, C9V, ecigwizard, TW, UKecigstore and Safercigs and maybe vapeescape, everyone else is a little guy who presumably, like us, have limited cashflow.
