Sucks to hear that. 99% of the dealers I've come across are shitty buisnessmen and have almost no real knowledge of cannabis at all. All their bud is the same, "it's good shit", or so they say. If you come across a new hookup, always ask them a lot of questions to test their knowledge, and never take their word for anything, buy small samples to test first to judge the quality of their product. A good dealer should know their bud and be able to tell you everything about it.
