The internet is a much better pricing source. Those mentioned and those in the Suppliers sub-forum have been vetted, if for nothing else, honesty. A couple that I used that have not been mentioned are Mt. Baker Vapor and Vape Wild.
When I see a juice label that says that it is premium, or select, or anything like that, I see it as a sales gimmick. There are many, many ejuice makers and competition is present. ONLY your taste buds know what is good. I used to note the price per milliliter after shipping as being my final cost and I stayed under 50 cents and was happy about the reputation of the vendor and what my taste buds said.
I DIY now, as others mentioned above. Much, much cheaper after you get set up.
Good luck!
