I have never used Litecig, I believe I heard some negative feedback at one point, but I can't remember what it was, unfortunately, and I could be wrong. I don't think it had to do with inauthentics, though.
I will note, perhaps you want to try vapecrawler. com if you are unsure about the site. You will get "good" prices (not necessarily rock bottom, vendor do pay a fee to use it) but "good" prices, from both USA and China vendors. It might give you something of a comparison point. You enter the mods or tanks or whatever you are interested in, and it will provide usually quite a few results. Etc.
Best of luck,
Anna
