Blur Dot is a great "bang for the buck" vendor. Blue Dot has a nice variety of flavor profiles, and the juice quality is generally good and sometimes great. For some flavor profiles you can find juice elsewhere that is marginally(but not a ton) better, but you will pay a lot more for it. For other flavor profiles, Blue Dot's product is just as good if not better than other vendors that charge much, much more. I have been totally happy with shipping speed, packaging quality, labeling, etc. Good sample packs/sizes are available as well as free shipping for relatively modest purchases (currently $25) If I had to limit myself to single vendor Blue Dot would be a candidate for its combination of product variety, product quality, customer service, and pricing. As it is, I like to occasionally splurge and pay more for juice that might be slightly better or slightly different, but if the wallet is feeling thin I am entirely happy to order from Blue Dot knowing that I will get a quality product at a reasonable price.
Later addition: After sampling some other vendors, as well as making additional purchases from Blue Dot, I can safely say that if I had to limit myself to only buying from one vendor, Blue Dot would absolutely be the one. Blue Dot has added several additional flavors that are of great quality, while still maintaining the same great customer service and pricing. I like to chase variety, so I will occasional sample other vendors. But Blue Dot is definitely my "go to" vendor. Blue Dot just does everything right. If you haven't tried Blue Dot....go out and buy a sample pack immediately!
