Var powder prices come down to purity. Plain and simple. How, and from who the raw materials are manufactured. If QV used the same powder suppliers as Denkall, then their var would be the same. There is no way that mg for mg BTG var is the same purity as QV, or as that is to BD etc. Think of it this way... you have exactly 1 gram of crappy weed, and 1 gram of AK-47 weed, you are obviously getting more bang out of one of them, but you also pay more for it.
