I'm looking for a bong for under $150, but I don't know where to search or what options are good cause I'm kind of a beginner with bongs. It seems like 5mm glass thickness is a middle quality, but I don't know brands. I looked around though and Black Leaf and Weed Star seem like they're inexpensive options for bongs. If anyone can show me a cool site that has cheap bongs I would really appreciate it, or if someone could give me some pointers on what to look for that'd be so great! And if anyone knows when Grasscity usually has their sales over 10%, like do they on or before 4/20 or Christmas or Thanksgiving?
