From what I've heard, tons of vape shops are trying their best to sell their e juice from their stores. To do so, they lowered the retail price, completely disregarding the retail price set by brewers because they won't be supplying any more juices. Most people are currently selling their e juice at night markets, authentic or fake. I'm not sure about the mods and tanks, but some of juice prices i've heard went down to even 12 rm! that's like half price of the stock price!
