I have ordered nic from Levy @ xtreme vaping and was very happy with it, I also ordered from some other suppliers with less satisfactory results. My question is should I go with Levy again or crystal clear vaping, or box elder? Box elder has best price but I don't want any more bad nic! I've heard both good and bad about box elder, nothing bad about levy or crystal clear. Any thoughts for recommendations would be highly appreciated! Thanks for your help!
