I can see why the forum might not want an actual poll for best supplier, since you can see there are some unscrupulous folks around plugging their companies incognito... having a poll would probably cause them to make lots of fake accounts. Anyway,
I just went through this whole thread to see how many times suppliers are cited, then, to approximate a poll. This count was
very subjective to my needs, namely, I'm looking for one highly recommended supplier, preferably in the US. Quite a few recommends were rejected for various reasons:
- If there were over 3 recommended suppliers in a given message, I didn't count any of them (from that message)... I don't want a laundry list, I want one recommend!

- If the user had very few total posts, I usually ignored their recommends (but not always)... they could be fakes or newbies.
- I tried to ignore the UK, since I'm interested in the US (but read on).
The results are (I can't post links yet):
www_PureSmoker_com really stood out for the US, with 7 votes.
Still, as Prof Daffy points out, one might get better prices direct from China. For Chinese sites, www_EastMall_net got the most votes, at 7. Note that this is also (formerly?) known as www_eCigaretteMall_com (which goes to EastMall), aka David Yang, a regular here. But a very close runner-up was www_BesteCig_com with 6 votes.
Although I wasn't counting UK sites, it is clear from going through all the messages that www_e-Cigs_co_uk was the winner. It may well have gotten more than 7 votes, if I had counted it.
Interestingly, there were 20 companies (location unknown since it's rarely stated) that got 1 or 2 votes, one company that got 3 votes - and then the rest are the "winners" cited above. It's a very bimodal distribution.
I conjecture that what's happened in this thread is that there are some popular suppliers, and then other folks wanted to give a shout out to some favorite that hadn't been mentioned yet (which sometimes got an "I'll second that!") vote. Which is to say that this long thread really isn't a "mini poll"... a lot of folks seem to be making sure that a company they like got mentioned, than repeating sites that have been mentioned.
Anyway, there's the tally. I hope some other newbies find it helpful... I just wanted one good company.

And I hope no one objects to the way I did it. If you did, then do your own tally.

This one took me an hour, as simple as it was. (Including this write-up.)
Thanks for having this cool forum! I'm sure I'll be posting more.
